agree with sospan... nothing wrong with Schutz if its used over good clean panels , awful stuff if its used to cover up things not to be seen like rust. It was never designed for that.
My AH has it under wheel arches and floor pans etc but not on the chassis, that's painted. Thinner stuff like dinitrol is inside cavities etc
I think its a case of using products for what they were intended. Schutz is a good sound insulator too.
