I know that some street rodders are using the truck bed liner. I just talked to a shop here that told me they use the spray cans of undercoating that you get at O'reillys or any other auto parts place.
What does that mean? The hard work is in the prep not the paint. You can use whatever your budget allows. I don't believe anyone will criticize the underside of your car unless you compete at shows. If you were you probably wouldn't asking the question.
I'm not a big fan of rattle can bed liner. The P/O sprayed the inside of the trunk with this stuff and I washed ever bit of it off with a garden hose...and he was bragging on how much time it took cleaning and prep before he sprayed the bed liner.
I wire wheeled the entire underside of the car while the gas tank, transmission, and driveshaft were out. Then I painted it with 2 coats of eastwoods rust convertor. Then I put 2 coats of industrial rubberized undercoating that I got from Lawson Products. It was a pain in the butt! But it looks really good and I now know that its protected from the elements.
I like this idea. I'm not looking to show the car but I do like the idea of knowing that the car is protected. Would this work in the trunk also or would a professional bed liner job be better?
Wash it, Scuff it use Crest chip Coat paint. Its made for lower rocker panels and a has a nice easy texture to it. Ive done my front wheel wells so far and Im going to do all the frame and floors little at a time.
POR-15. And the good thing is that stuff actually LIKES a little rust to grab onto. In fact, to correctly use it, you should let it get a light rusty surface to pit it, or if clean metal, get it wet and let it sit outside for a couple days, brush off the surface rust, and paint the POR-15 on. It will never rust again, and comes out looking like black powdercoat. But it fades in direct sunlight, so great for under the hood, in the trunk, under the car, but not as a final paint coat on the outer part of the body.
I like the POR15 also. To get past the sunlight issue, paint it with your choice of black(satin, gloss, flat) while it's still tacky. You have to scuff it well to get paint to stick after it dries. All the info you need is in the instructions that comes with the kit.
