Trunk and Floorpan Repair Kit Overview

RustSeal - Stop Rust - Paint Over Rust

You can maintain the integrity of the structure with no ugly welded seams. Our easy step-by-step instructions make it simple to restore floor pans, trunk pans, pickup truck beds, etc.

You'll be amazed how complete it is... More of what you need ... Everything you need is at your fingertips.

KBS Coatings’ 3-STEP SYSTEM of RustSeal (a rust preventive coating), KBS Klean (an industrial strength water-based cleaner / degreaser) and KBS RustBlast (a powerful rust remover / metal etch) 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, this superior coating 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.

Rating Easy and looks great
I researched online for a product that will stop and seal the rust in the trunk of my 1959 T-Bird, and decided on trying KBS Trunk & Floorpan Repair Kit. I had some rough pitting and a few minute holes in the trunk floor and needed something that will look good. I followed the directions that comes with the kit. First, clean out as much rust, dirt, and grime on the areas you're fixing. Then you constantly keep the areas wet with the included Aquakleen, then rinse it off. After it dries well, you use RustBlast the same way, keeping it wet, then rinsing off until it dries. When you use the final product, Rust Seal, it's almost as thin as water. For the whole floor of the trunk I used less than half of a soda can. After a couple of hours drying, I put another coat, and repeated for the 3rd coat. I had a few pinholes in the trunk floor, so I used some of the Backbone reinforcing mesh, and a small wad of NuMetal on a larger hole. Everything was real easy to follow and use. It just takes patience waiting for dry times. It was so easy that I can't think of a negative thing to say. I used the gloss black, and it looks great!

Rating Great product...better than alternative products
I have used the other brand of kit as well and this system is as good if not better and you get enough product to do a much larger area...and it costs less! Great experience eliminating rust from my floor pans and sealing them to minimize future issues. Requires a few days of time going back to apply more coats, but works as advertised.

Rating This product works great!!!
This saved me from replacing my oil pan on my truck. They would have had to pull the engine to replace it.

Rating hot ****
Product truly exceeded my expectations. Used the rustseal & multiple layers of fiberglass cloth to repair the rusted through floorpans of my '64 Falcon. The seal dries rock hard & even with my 210lbs. the floor doesn't deflect under my weight. The rustblast is slow going, you have to let it work & you have to keep it wet but it does a great job of eliminating the rust right down to fresh virgin metal. I'm confident these floorpans will last at least as long as the originals.

Rating Durable Finish
I am in the process of updating a NASCAR Busch Grand National Stock car to current racing specs to run it in amateur road racing. One of the items I needed to address was the expired fuel cell and associated pieces. The cell is mounted in a recess in the trunk area of the car. WHen I removed the cell, there was significant corrosion in the recess. In addition, I plan to re-coat (over time) the entire interior and underside with a red color similar to the existing color. Normal paint won't cut it. I purchased this kit to try out the product thinking that if I didn't like it, the coating would be limited to the trunk area. As it turns out, I am happy with it and, over time, plan to redo the entire interior and underside of the car with the Oxide Red. My only neagtive is the number of steps to get to a proper finish. However, this may be the nature of the beast and I need to accept this to get a quality result.

Rating So far so good...
I'm using KBS Coatings to repair some not-so-minor drip rail/rain gutter rust issues on a 1970 VW Bus. The instructions are very easy to follow, and the kit comes with everything you need to do the cleaning, priming and repair/patch work after you've thoroughly prepped the spots needing attention. There is plenty of BackBone to MORE than address the holes of my project. I had a little bubbling occur, but I'm sure it's because I applied the coating product a little bit too thick (the fiberglass soaks it up and then made a little glob at the bottom of the backing). Product dries fast and is extremely solid. Will be applying a top coat of enamel to protect further and cover up the not so great Off White color (which goes on white, but turns almost yellow when cured). My next order will be regular White. Haven't used the Epoxy or needed the Thinner...YET. Will be using the Epoxy to fill some cracks on the front nose panel to get me through this winter - can't wait to try it!
