Agree with Huck.. Save your money
I have Wrisco flat black on my car and it is terrible.
Unfortunately I used flat black on my entire car plus bought 2 extra sheets and I'm pulling it all off and...
I agree with Huck stay away from the flat black Wrisco.
I have Wrisco flat black on my car and It is a waist of money. Same thickness as gloss colors but very soft like metal 1/2 thickness.
Mine are bolted to the frame because my car straps to the ramp overs not the trailer floor.
The tire rack,cabinets and anything heavy I mount to the metal studs or runners in the walls
