Getting ready to coat the interior of my tub. I’ve wire wheeled, cleaned, sos padded, por 15 metal prepped. The tub is solid, some pitted areas, is there anything thicker consistency I can coat with to hide imperfections beside bedliner (I don’t want the scratchy surface)? Want to match dune beige-ish, it’s a trail rig, not a show piece. Have read for hours without a good answer and many threads 10-15 years old too. Thx!
