System Sampler Overview

The KBS System Sampler Kit contains everything you need to clean, prep, and apply two coats of RustSeal on up to a 12.5 square foot area.

KBS Coatings’ 3-Step System of RustSeal (a rust preventive coatings), KBS Klean (an industrial strength water-based cleaner and degreaser) and KBS RustBlast (a powerful metal etch and rust remover) is the most effective rust and corrosion prevention system available today.

RustSeal chemically bonds to bare metal to form a permanent, moisture resistant finish that is flexible, yet won't crack, chip, or peel. Because RustSeal is moisture-cured, RustSeal is made even stronger by continued exposure to moisture.

RustSeal is also highly resistant to some of the most aggressive chemicals such as acids, alkalis, salts, abrasive materials, fertilizers, coal dusts, solvents, oils, and other refined petroleum products.

Works well.

The process is straightforward….but watch video and follow instructions. I would rate it a 5star but only gave 4star because I had to destroy the lid of the paint tin to get it off. I used the recommended lid opener but lid is so deep the opener won’t lift it high enough to get it off. Once you get lid off (you’ll be frustrated by now) remember to properly stir paint. This is important. Paint dries to a nice smooth, level finish. Apart from getting lid off paint tin, I’m happy with the results. I’d buy it again and recommend it.

Very reliable

I saw your product while doing a giggle(lol) search for my rebuild/restoration. Your product line checks off all my boxes. Easy to use, comes with instructions and support if necessary. Has everything I need to complete my project without causing too much of a stir from the CFO(the wife). I know the competition is intense but it's a great fit. No pics to post. I needed a good cleaner and I choose the KBS system. I haven't primed/sealed/base coated/inter-coat cleared or cleared as of yet.

Trial kit

I ordered the trial kit to coat the front suspension/steering components of my 1994 Cadillac Concours. As a car used in the North East winter (salt!) it had some significant surface rust in these areas. I used a needle scaler, die grinder, and angle grinder to remove as much of the rust as possible, cleaned with the provided solution, used the rust converter per the instructions, and applied two coats of the Rust Coat. The results were very impressive. The suspension/steering parts look like new with the smooth gloss black finish, The only issue that I had with the kit was that the rust converter solution quantity was not sufficient to do the job on the first side. Fortunately I had some of a similar product from a different supplier and was able to keep the parts wet during the conversion process. I ordered extra rust converter with the next kit that I ordered (for the other side). I'm not confident that one of the kits will cover 12 square feet as advertised. I used the products as carefully as possible (getting a 2 mil paint coat with a brush is very difficult) but used a full kit + for each side of the front end suspension and steering parts. I will definitely purchase these KBS products when needed in the future. Each product performed admirably. The finish is beautiful, extremely hard, and should last the life of the car.

Does the trick

If you read my review of a year or two ago you know I'm a convert to RustSeal. This time I bought the whole Cleaner-Prep-Seal Kit for two jobs -- the interior hex nut on a garbage disposal (a re-application, as I carelessly poured acetone down the sink and kind of fouled up the original job) and priming and painting a rusted section of a door. Problems solved. Wait for dry-ish weather, wear rubber gloves, follow directions, take your time, hard to go wrong.

mower deck overhaul

2 different batches of paint. 1 very thick (old) and one very thin (new). The old paint was used up very quickly and was disappointed that it didn't do the whole deck, it barely covered one side. Ordered new bach and now have left over paint as it covered thinly, even tho I had to add extra coats to get the correct mils. Very frustrating product. Hope it holds up as well as you advertise.

Great dealer, great service..

I bought the rust sealer to put on the bottom of my 48" lawnmower deck to save it from rusting out from the abuse it takes, and also hoping it would increase the output flow going to the bagger. I had made a leaf catcher to replace the bagger because with all te leaves I have, emptying the bags every 10' as the bags would fill up that fast wasn't an option. So I used the sealer for two reasons and it worked great. I had plenty to put it on good and thick. I called on a Saturday when I was mixing the contents up and I had a question about the mixture and I got a call back in a half hour which I appreciated as I wanted to get this done. So it's done and the leaf catcher works fine. Plenty of air flow coming out of the deck and into my leaf catcher, plus my deck is sealed. It will probably last longer than the rest of the lawnmower.

GREAT KIT

This is a really great kit. I purchased it to clean, prep and prime two rims on my 1941 Indian 741. Plenty of paint to do not only my rims but the hubs and a old seat pan! I would add pictures but am not that 'techno' savvy. I like that the prime is available in numerous colors so you see the contrast when top coating. Would buy again.

KBS....a good choice

Prep was a bit drawn out, but final program quality depends on prep work. I would STRONGLY suggest heavy (7 mil at least) gloves for both the prep work and FOR SURE the application of the sealer. It's been about 3 weeks since the process and so far (cutting side of lawn tractor/mower deck) are fine......no large pieces of rusted material on the lawn after mowing. Sorry, no pictures, either before or after. I'd recommend the KBS system. Customer service alone is worth it. And the cost, DIRECTLY purchased from KBS was more than fair.

Not as I expected

I’ve used KBS Motor Coater with great results so I thought I’d give Rust Seal a try on a portion of my frame. I prepped following the included instructions, using the proper chemicals included in the kit. The resulting finish was neither Satin Finish nor smooth. The dry coating is quite shiny, and brush marks were quite evident. The portion of frame is covered by the fan shroud, so I left it. Don’t know if I will use this on the remainder of my visible frame.

Awesome.

Far from professional but even I couldn’t mess this stuff up. Used it to coat some new metal rock sliders and supports on my Jeep... applied it in too cold of weather over a combo of steel and seam sealer, and let it sit over night in below freezing temps. Still cured rock hard by morning. Leveled itself out great (luckily helping to bury some of my metal working goof ups) Highly recommend

Rust stopped!

I was a prior KBS customer, buying their clearcoat. I lived their website and great customer service, so I knew to come back to them for rust relief. I did the small sample pack to tackle two small rust spots on my car (rocker and quester panel spot). I thought after doing the black gloss Rustseal with a brush, it would stick out like a sore thumb. However, it self-leveled enough where I don't really notice it! It's still there if you look, but a glaring blemish that I need to address right now. I absolutely love the customer service I have received over the years from KBS and will be a customer for life!

Q: What if I allow let RustSeal to completely dry and decide I want to add another coat?

Asked by: Fred - 4/2/2020

A: When RustSeal has fully cured, scuff the surface slightly with 300 grit and then wipe the dust off with a water based cleaner like KBS Klean. Then apply more RustSeal. Always thin coats and never heavy coats.

Q: At what step should body filler be used if needed?

Asked by: Randal - 8/23/2020

A: It is always best to prep and seal the surface first before you do body filler as this helps to prevent the body filler from popping off. So, clean the surface with KBS Klean, etch the surface with RustBlast and then seal the surface with RustSeal. When the last coat of RustSeal has cured 24 hours, scuff slightly with 300 grit and then apply your body filler.

A: Yes, you can coat over RustSeal with automotive touch-up paint. Simply scuff the cured RustSeal slightly with 300 grit, wipe the surface down with a water based cleaner like KBS Klean and then apply your automotive touch-up paint.

Yes, you can clear coat over an automotive touch-up paint with DiamondFnish Clear. That is an ideal application for DiamondFinish Clear because of its durably, ease of application and it produces an incredible looking finish.

Q: Is the system OK over existing paint? I have some areas of surface corrosion both inside the trunk and engine bay, and a few small areas on the exterior. Will the clean or blast damage existing paint ?

Asked by: Walter - 9/14/2019

A: Yes, you can use the KBS 3 Step Rust Prevention System over existing paint when needed. To do this: Wire wheel the existing paint to remove any loose paint. Clean the surface well with KBS Klean and a scotch brite pad. If you have any bare metal spots, etch these spots with RustBlast. Then apply RustSeal over the existing painted surface. Always thin and never heavy coats of RustSeal.

KBS Klean and RustBlast will not harm existing paint that is fully cure when the directions are followed.

Q: I want to spray RustSeal and need to thin, what do I thin it with?

Asked by: Rick R - 2/26/2020

A: When spraying RustSeal: Spray pressure of 35-45 psi (250-330kpa) for siphon/pot guns and 25-35psi (170-250kpa) for gravity/top container guns. As a general rule of thumb, we recommend a 1.4-1.5 tip size. Thinning is not generally required but if needed 5%-10% is normally adequate. Use KBS #1 Thinner or Xylene only which is a slow evaporating solvent. Do not reduce RustSeal with lacquer thinner. Also remember to clean your spray gun immediately after using RustSeal.
