buffing help needed

OK, here's the deal. I am using PPG 2021 clear. I am using just a tiny, tiny, tiny amount of accelerator in the clears (on occasion), but I don't think this is effecting my problem, because I seem to have this problem regardless of weather or not I put any accelerator in my clears, and the amount of accelerator I am using is so minute it can't possibly be having much of an effect on dry times. Anyhow......
After shooting 2 or 3 or 4 coats of clear, I wait until the next day (at least 70 degrees temp's are maintained through this period) Then I wet sand with 2000g, use 3M "Perfect-It" III super-cut compound on a 3m "Perfect-It" white pad. I typically buff it pretty good, wipe the part down with a 50/50 water/rubbing alcohol mixture, dry it off, then use "Race-Glaze" polish and a 3M "Perfect-It" glazing pad to bring back the shine. I am not convinced that I am getting enough "gloss" back after buffing. I mean, it's shiny, but not as deep and glossy looking as the clearcoat before it was wet sanded and buffed. /ubbthreads/images/graemlins/help.gif On occasion, I have tried buffing it with the white pad/Perfect-it compound, wiping it down with the 50/50 water/alcohol mix, buffing it AGAIN with the white pad/Perfect-it compound, and then using the Race-Glaze on the black pad, but I just can't seem to get that "deep, deep, gloss shine"..........

Any ideas???????

After you spray it it'll dry into 'the' shine,but once you cut and buff it you actually lose some gloss.Sandng it flat and buffing gives the illusion of a beautiful job but if you can get it perfect on the reclear don't touch it,side by side you can tell a big difference/

Been there, done that. Rex is right. I swear I've tried just about all the buffing techniques out there, but nothing glosses better then a perfectly flowed out untouched clear coat.

try letting your clear dry for a week or so,before sanding and buffing,curing takes time,you may be gettings solvents still coming out of the clear after you buff that will reduce overall gloss.it will be harder to buff but should be worth it.

a good friend of mine made a few suggestions:

1) use of a REAL buffer (vs the drill based set-up I have been using since my buffer motor burnt up /ubbthreads/images/graemlins/ohwell.gif)
2) using the #m glaze instead of the Race Glaze
3) using a final buffing product (I forget the name of it, but I'll remember it when I get to the shop!) after the first 2 steps

I just tried buffing out a day old job with a foam pad on a DA sander with 3M compound. It just didn't get it done. I switched to a real buffer with the same compound then did the final touch up with a 3M finishing glaze and the foam pad / DA combo. Made all the difference in the world.

And by then the clear had been on there for a week so that may have helped.

Sorry,I never really answered your question.2021 is pretty slow stuff so buffing 2 coats the next day will be fine usually but 3 or 4 coats should sit another day.Try 2042,it won't lay quite as flat but still leaves a nice finish buffed.If you need to do a flowcoat sand the 42 and coat it with the 21,then you can just nip the dirt nibs and slide over the whole thing with polish.I prefer the 21 but it just takes too long to dry.Stick with the same system too like stated for best results too.
