A couple of questions then:
How can you clay such a rough and porous surface without sheering off your clay on it and creating a mess? Especially on Chevelles as they typically have pretty rough tops.
The material is not that porous. Especially when its wet and you use APC as lube
The same goes for the platic razor technique too. Body shop overspray is pretty fine and tough to remove from painted surfaces, let alone a vinyl top. (Especially when baked) I can't see how that tool used on a porrous surface would work? It's not like you are able to chip away at a fine mist that's covering this porous surface? Maybe when the overspray is the big blobs/spec style.
If you glide it across, it will pickup whatevers on the top. Down in the valleys (porous) is where you going to have to have another plan
I agree with the APC method. Especially if you pre-softened the surface with water. Letting maybe a couple of soaked towels (water, not APC) sit there for a while loosening up the bond.
:iagree:
You'd have to scrub pretty hard to get BS overspray off with Solvent (especially Laquer Thinner) which is pretty strong stuff. I'd be very carefull using that on vinyl as it *could* quickly discolor and melt the material.
