    Okay guys, I've sanded down the body on my K5 (600grit, then 1500 and then 2000) and have used rubbing compound to put a semi-mirror finish on it. What I'm looking for is how to get that complete mirror finish on it. Yeah yeah, I know, it's an off-road vehicle so why do this you ask. Well, I've puts many, many hours into sanding and I don't think it'll take that much more work to get it to that point so why not do it, besides it'll look very nice. Scratches aren't a worry because those can just be sanded out again. So what's the next step after the rubbing compound?

    Polish it with 3M's "Finesse-it" compund on a high speed wheel, followed by a coat of carnauba wax. Should give you the finish you're after.

    I've never used the glazes before, so I really can't say if they are any good or not. I did have a truck that had been sprayed with the "poly-gly-coat" before, and it was horrible - every few weeks a big section of it would start crackling and looking like hell.

    I agree, machine polish then wax. Is the paint base/clear, or a single stage? If it's got clear on top, you may want to shoot 3, 4 or even more coats of clear on top. That's how you get that real deep color look.

    It's none of those ... it's been powdercoated and I don't want a clear coat on top of it because if I get scratches I just want to sand them out and repolish it.

    Pugsley: I think I'm using 3M's Finesse-it. Is that the stuff that comes in a white bottle that will only cut the finish so far and then "quit" cutting? If so then that stuff hardly does squat on powdercoat with and electric buffer, but any little bit of polishing works for me (too much time on my hands obviously!)

    Simple in theory. Pull off all the parts, strip them of anything that won't stand up to a 400 degree oven (eveything), send the parts off to a chemical stripper, send parts to powdercoater, get damaged parts back (URRGGHHH!!!), clean all the innards of the doors/tailgate and reassemble (with LOTS of sanding to remove the orange peel effect). Pics will be posted soon when the project is done once I get a camera and learn how to post them.

    That sounds like the stuff. Are you using a high speed buffer, or an orbital? If you are using an orbital, it may pay to go to a slightly coarser grade of compound, like 3M's "Perfect-it" with a foam pad.

    I'm using a WaxMaster random orbital buffer than has a 1 inch foam pad (from Home Depot). I'm not sure of the speed but it's suppose to be used for waxing cars. The rubbing compound is 3M's heavy duty rubbing compound, it may be the Perfect-it but I'll have to check when I get home.

    Thanks. Looking forward to seeing the pics. Powdercoat is some tough stuff. What kind of costs were involved in a project that big? Seems like it might be a little expensive.....

    For a body shop to do the same thing, strip it down to bare metal and repaint it, they wanted over $5k. This is the only body shop that I would trust to do the quality of work that I was interested in. This way was $2k for the powdercoat and 700 for stripping it. A little more than I was first quoted but that's ok. It looks good so far for the price but we'll have to see how well it holds up to the elements. An expensive experiment but if it works great, if not then I'll do the old tried and true method.

    If it is the Perfect-it, and it's not getting you anywhere, try Meguiars' medium-cut cleaner. pugsley.alloffroad.com

    I'm using the Perfect-it (if that's the heavy duty compound I'm using) to polish out the 2000 grit sanding and that works great. After that I use the Finesse-it which hardly does anything, but maybe it's cut it as far as it is suppose to. Nice shine but not quite where I want it Then I tried an off the shelf wax on one piece to see what kind of shine I can get. I was just wondering what to do after the Finesse-it. I'll try the carnauba wax and see what that does.

    Yep, Perfect-it and Finesse-it and a 3100 rpm polisher.

    OK - the wax should do the trick now. If not, I was looking into the glazes, and 3M and Meguiars both offer one that sounds really impressive - might be worth a shot.

    I think I'm going to try the carnauba wax first, I read up on that. And since you've never used the glaze then I think I'll skip on that until I know more about it.

    A buddy of mine used a glaze on his 67 Nova II and it looked great. Doesn't last as long as a wax finish but looks great and is very easy to apply.

    But it sounds like you are into using time, wow.... sounds like a lot of sanding.
