I am getting ready to prep and paint a truck bed with a nitro-cellulose based paint thats "permanent" and very resilient to water,corrosion, chemicals, comes in many different colours, contains 46% solids, is textured, can be glossed or cleared or matte flat. It can be removed with strong chemicals or mechanical sanding with coarse grit,(36). It would have some interesting uses in the trunk, inner body floorpans, underside, even underhood for racers or those not desiring an oem finish, I have seen it used in Hot Rods, trucks, cars, equipment, fiberglass, ect, what 'drew' me to it was the hard 'ceramic' like finish and the ability to resist corrosion. It covers everything, welds, cuts, gouges, any smaller imperfections! If interested I will show the whole procedure of application in a truck bed from start to finish. Let me know
