Does etching primer etch the gl***? I've tried laquer thinner and brake fluid and a razor s****er to try to get the primer of the gl***. The PO sprayed the primer 10 yrs ago and didn't fully mask the gl***. Any ideas??
I've already tried thinner and brakefluid with a razorblade s****per. This has been on there @ 10 yrs. Anyone have any other suggestions. I'd hate to buy all the gl*** new.
Etching gl*** requires a period of exposure to a strong acid. I doubt the gl*** is visibly etched. While the primer may be on there really well, I believe it can be chipped off with some effort and either a sharp s****er or fresh single edged razor blade. Scotch-brite can make visible scratches in gl***. To a lesser degree steel wool can too.
If you have pits in your gl***, the primer may be sitting below the surface making it harder to get it off. Otherwise, get a sharper razor blade.
DO NOT USE GRAY SCUFF PAD!!! The clay bar will also damage it. A razor blade will do it if applied correctly. Steel wool will remove any small amounts of it. Etch primer does have phosphoric acid in it, so it may have etched the gl*** a little if it were applied heavy enough.
AFAIK gl*** would only be etched by flouric (sp?) acid. Doubt that you'd find that in paint. Mechanical means (can scratch the gl*** though) or careful use of paint stripper or solvent.
