Hey guys i'm new here i've spent the past week or so reading my way through from the first post and i have just started painting my camaro rustoleum gloss black..
i have a few questions though
on my first coat on the hood i sanded with 100/220/400 and it felt completely smooth to the touch. the first coat went on alittle thick and i could clearly see some sanding marks that must've stayed through from the 100g sanding. to continue should i just wetsand with 400 until its smooth again or must i completely sand it off and start over?
also this weekend im looking at buying a polisher. i'm a college student currently on a break and i dont have much money. i've read great things about the PC 7424, but i've also been looking at a chicago electric rotary from harbor freight. the rotary is only 50 bucks
would someone with no polishing experience but an exceptionally high learning curve be able to use the rotary to polish or will it be worth it in the end to just buy the porter cable?
thanks

I don't think the Harbor Freight one is random orbital like the Porter Cable. If you are not experienced, you are more likely to screw something up if you don't have the random orbital feature.
BTW - maybe you could rent one from your local hardware / tool rental store. You really only need it for a day, to buff out everything when you are done. Probably only cost you $20.

I am so mad I could . I only waited about 24 hours before I started polishing should I have waited longer? James

well from what i've read is on your final coat to wetsand with 1000 and if you want 2000 and then polish to get a glass shine, but going from 600 to polish is too much i think Quote:

I think i picked mine up at autozone....bout 1000, 1500, and 2000. but what i think the real problem is that the polisher you are using is not powerful enough. i had the same problem. so I jsut thinned the last coat very thin and left it like that with no sanding or polishing....until I get(can afford) a good polisher!!

I'm thinking its both: final sand and crappy buffer. 600 grit for the final sand is not even close. You gotta get to at least the 1000 grit wet sand stage before you try and polish.
And NO - 24 hours is not long enough to wait before you polish.
And - most people do not get good results with the cheapo $30 buffer. There have been a few exceptions, but not very many.

Don't use acetone unless you have an oxygen respirator pack on. The fumes will kill your brain and your kidneys. It also makes one heck of an explosive mixture when atomized in the air and finds a spark ( yes something as simple as the spark of the rotator brushes in the electric motor of cheap electric spray guns.
There was some discussion earlier in the thread about the right mixture or flow rate to cut your paint with mineral spirits to get a good vaporization of the paint when spraying.

Just an FYI, as you seem to have given up the rollering. I waited 30 days before final sanding. My final sand was 2000 wet - any good auto parts or auto paint store will have that. I am lucky I guess as a friend has a Festool Rotax polisher - $800 here in Australia. Cut it twice with that and then polished. I am using Brightside BTW gloss black. Best way I could describe the finish is black chrome. Awesome. Incredibly smooth. My only issue is I have some marks in one of the layers of the paint - trying to figure that problem out now. Cheers, Frank.

Well you could drive around in the final coat. It wont be great, but not terrible either. Mine has a decent shine, not much peel and very little dust inclusions. Drive it for 30 days, then do the final 2000 wet sand and polish. Just a thought.
Cheers, Frank.
