Hello I'm looking for suggestions for products to use on the bottom side of my body. Body will be blasted and on rotisserie. I've heard about bed liner and rubberized coatings but I have no experience with these products. Any input would be great.
I found this but not sure.

I sprayed the bottom side of my tub with Upol Raptor. You’ll need the gun, but it’s only like $30. Easy to mix, easy to spray, tough as nails. The standard black came out with a satin finish and it’s not overly textured.

That product is very heavy and provides aggressive texture I'm not sure what you're looking for but some of the bedliners like he mentioned are a little smoother. I sprayed the underside of my car with a bedliner spray from sem
and it's on the smoother side compared to the 3m you posted.

If you are blasting clean, I would epoxy prime and use U-Pol Gravitex. U-Pol Raptor would work as well. Body Schutz is more rubbery and never fully dries. Gravitex gets hard and it is paintable.

I used upol raptor. You can buy kits that come with a gun. I used this kit on the underside of my monte. It took all of it.

Easy to spray, tintable, paintable, and doesnt come off easy. Ive accidentally hit edges with wire wheels without damage. Just strip, brush on epoxy at the seams,seam seal, 2 wet coats of epoxy and spray the raptor. I plan on buying 2 more qts for my wheel wells and trunk also.

What is a decent brand of epoxy primer?
How does epoxy primer react with light rust. Jusy curious not that I'm Planning to paint over rust but there is always a chance a seam is not perfectly clean.

Ive used Body Schutz for years. Probably started in the early 80s. Ive used it under both of my Malibus and even a couple of my trucks when they were new.
Now that Ive told you this I have to say if I could do it all again I'd use Raptor. Its a much better product. Crank up the pressure when your spraying it and it comes out a little smoother.
