I happen to be out looking for a new truck when I came across a truck with the spray on bedliners. The spay on bedliners are rock hard and block water from eating the bed up. Then I started thinking why not do the bottom of a car this way or even the interior floor pans. You would end up with a bullet proof, water tight undercoat seal that would even provide insulation for a/c cars and block road noise. I think the advantage of the spray on bedliners would be that you can get more of a showcar finish than just undercoating. I have been thinking about trying it on my car, what do you guys think about it.
I actually did this to the interior floorpans of my last maverick, along with the wheel wells. The only reason I didn't do the undercarriage is because it would involve getting the car on a lift somewhere I can pressure wash the undercarriage clean, remove all the lines, and paint it. I just didn't have the resources to do all that, thought I'm considering doing it to my current maverick. You can buy some pretty high quality stuff in a roll on/brush on application too. The best I've found is called Herculiner. I actually coated an entire Ranger with it, and it's holding up well. Here's the truck, really wish I still had it.
Thanks. I loved that truck, but I sold it to put a down payment on my Pathfinder (current daily driver) and free up some funds to buy my current Maverick, so it went to a good cause. I sold it to a work buddy, so I still get to see it, but it's just not the same.
Im redoing my carpet, putting bucket seats and run my wires for the speakers all at once, and Im using Raptor Liner spray on liner
After I coated the floor with Rust Bullet I used bedliner on the interior floor...inner quarters...inner fender aprons and trunk floor. I will be using it inside the doors soon. I notice when I closed the doors with no seats or carpet it sound solid. Stay away from the rattle can stuff.
It was fairly labor intensive to do the truck (with all of the masking, and rolling such a large area) but it shouldn't be too hard to do a trailor. The one thing I would suggest is looking into a UV topcoat for bedliner, as this stuff started to fade after a few months.
They did it on "Musclecar" a few years ago, http://www.lizardskin.com/. If you used something like Line-X it would add alot of weight, and thickness.
I thought it looked like Duplicolor! Because im doing the same thing with my car right now. bought the can at kragen..
I say anything you can add like products mentioned here will help keep a solid car more solid, and a pin hole car can gain a few more years use for sure.
this is exactly what i have been planing to do to my comet when i finally get to working on it. my buddy did int to the floor of his 78 dodge truck. he started with a product that converts any remaining rust to primer. then he went over it with the roll on liner from auto zone. it came out really nice and that was the point when i decided i needed to use it as undercoating and to coat the floor of my car.
