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.

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.

Very good product, had a few small holes and following the directions they were covered very easily. The process is a little bit of work but the finished product is well worth it.
