Great stuff that POR15 :thumb up: :thumb up: :thumb up:
I've spiffed up many an undercarriage item with it over the years. My latest items were my E46 brake calipers and suspension links.
PS: I just completed an 1100 mile trip from Texas to Wisconsin pulling a 5x8 U-Haul trailer loaded with granite, so maybe a total trailer weight of 4500#.
My aftermarket hitch rig survived
