Rating kbs diamond clear coat and #1 thinner
I think it is a very good clear coat I use it on fishing lures crankbaits and it works very well and is very durable so far I also like the easiness of it dip it and hang it I usually do 2 coats but I love it no more mixing 2 part epoxy for me and I think its more durable than 2 part epoxies so thanks for a great product and if you have any new products I will be glad to test them for you again thanks

Rating Thinner Reduction Use
Application: Reduced 10% and HVLP shot at 35psi. 24hr dry. Knocked off any dust nubs with 320grit. 2nd coat laid on a little heavier now that I have a feel for it. After 1st coat your could still see the pits where rust was, after 2nd coat they are gone - Talk about flow out! Used a guide coat and sanded to verify everything is filled, no sign of the pits at all. Then a 3rd double wet coat reduced a bit more for a smooth finish. Really did not need the 3rd coat for filling, could have left it at 2 coats and skipped the guide coat. Heck I was expecting to use 2K primer surfacer to get it all filled and smooth.

Rating A Great Covering Paint
I have been using KBS Coatings for several years now and find them to be superior to other similar products. I especially like the Customer Service and assistance from this company. Being in the painting business for well over 50 years has given me the opportunity to try many products. I like this one especially.

Rating Thinned Diamond Clear for Preval Sprayer
When it come to painting using anything butt a rattle can I was brand new to it. Was my first time praying KBS products and having to thin the paint for use with the Pre-val Sprayer system. You need to use this product as instructed and not how you would normal treat other paints. Of course it is a paint thinner but I'm talking about using KBS paints like rust seal. When thinning for use with the sprayer I found that %25 was just5 about perfect. I am in a warmer climate and it was in the middle of summer so folks else where I would assume may only need about %15. All in all quite happy. Pre-val doesnt make you a star either and I dont think they are just a good as a professional spray gun (even though I've never used one). Didn't seem as if the paint atomized.

Rating Aids in Clean Up
Makes KBS coating more workable on multiple coats. Also it will aid in clean up if you get KBS coating on skin or drops on floor etc.
