hmmmm, missed this one....
Hate to say it, but your gonna be ch*t outta luck... Sorry...
Couple reasons being.....
"Buffing" thru the clear isn't gonna happen.. your just gonna wreck the base... base is very unforgiving in that regards... I mean you could cut thru it with some super duty compound, but its just gonna do a f*cked up shine job on the base, that'll need to be sanded and recoated anyway.... base is not designed for that.. plus, you'll be buffing your arse off... And more than likely actually going thru the base in areas.. I mean, you could try it, but it'll be a good amount of work and the result are prolly gonna look like ch*t..
your only real option is to sand the clear off, which will sand the topcoat of base... then throw a couple coats of base on to freshen up and reclear...
we did tons of those factory recalls back in the 80's...
maybe start redoing it panel by panel? sand/strip it down, prime.. then move on to the next panel when you have time...
