Polishing fiber glass body

I have a real nice glass 41 Willys that I really can't afford to paint right now. It has a nearly perfect body. No mold lines and very few imperfctions. It has only a little repair done on the edges as it was removed from the mold. these are primed with a primer that is very hard. I tried boat refinisher which is a very mild rubbing compound and even with a varible speed polisher it is tough to buff this stuff off. I also experimented with some black Krylon over this. that I can polish out nicely if it has dried several days.

That's fine,
But my real problem is that I'd really like to polish the whole car. It's nice now but I've seen others with just the gel coat polished and they look fine.

I'm sure I'm sure I'll need several grades of rubbing compound but I'm in the dark as to what I need. I have a nice varible speed polisher and several bonnets. I can get more.

So Body guys ..... what do I need and what is the proceedure.

hi,since i cant see your car or the condition the glass is in,heres the scoop.water sand (add a little dish soap) the entire car with 600 grit paper (i use an air jitterbug) after you finish, wash the car, then water sand Again,a little dish soap, with 1000 grit. again wash the car. then use the coarse rubbing compound with the buffer,after you finish,wash the car (are you tired of washing the car yet?) then buff again using the polishing compound (very fine) i have been repairing fiberglass boats for almost 40 years,and this is the system i use.

thanks boatbob,
Almost all of the car is glass smooth. It actually was polished at the mfg. They repair a few edges that get chipped or whatever when it is removed from the molds. these are well blended in and are primed with some primer that is incredibly hard. The overspray is only removed with the coarse rubbing compound at best. There are some places with small swirl marks about what you would see with 400 paper.

As you noted the 600 wet should take these out and the 1000 takes out the 600 scratches and buff the rest.

I think I'm going to have at it just as you indicated. I think it's plan.

Thanks a lot

oh, any recommended rubbing and polishing compounds???
