Car is a 93 MR2 with severe swirl marks and moderate oxidation/fading. I've completed the engine bay in back and one side and it's actually coming back nicely. I'm starting on the hood and under a halogen light the swirl marks are fairly evident. I'm using a PC and Meguires Heavy Cut cleaner (#4) and 3M medium compound with a yellow pad. I've completed two sections on the hood and neither product on the highest level will remove the swirl marks. The oxidation is gone but swirl marks remain.



Couple questions: Should I go more to a more aggressive product/pad or keep going over each section with what I have? I'm a little afraid of polishing throught the paint as some corners of the hood already are to the primer. Also, what's more aggresive the 3M medium compound or #4 heavy cut cleaner? Reason I ask is the 3M will actually haze pretty bad, the heavy cut cleaner doesn't haze at all, neither have removed the swirl marks.



Here are a couple pics, thanks!

I don't know the products you use, but.....



it almost sounds like you could use a less aggressive product/pad

than a heavy cut to finish with out swirls



I am sure others will chime in with helpfull

info about the products that you have
 
Meg's Heavy Cut isn't meant to be used by PC (it needs the temp/speed of a rotary to break down). Maybe try some optimum hyper compound, that'd be my choice on something like that. Make sure you're going nice and slow, with plenty of pressure, and then a few passes should make some difference.

That's good to know, it appeared the #4 heavy cut had zero effect on the swirls. Tons of paint on the pad though :)



Which is more aggressive, 3M medium cut or Meguire's #4 heavy cut? The 3M hazed pretty bad which led me to believe it might be more aggressive. #4 didn't haze at all. Just curious...
 
what other polishes do you have on hand?



OHC and a yellow pad should remove those on speed 6 on a PC. I say should because I have no idea as t just how bad they are in the pic you have, and how hard the clear on your car is . . . .



Either way, You will need to work the product for a long time to see results . . .

What is OHC? I only have the Meguires Deep Crystal Polish in steps 1 and 2, Klasse AIO and Sealing Glaze but I don't think this is aggressive enough. I also have some Menzurna FP, I used all my IP unfortunately. I do have some Scratch X but I think that is to be applied by hand, will it work with a PC? Then I have the 3M medium compound and Meguires #4 heavy cut compound which I have been using with no results.



Oh, there is no clear coat on the car, it's a single stage paint.
 
oh im sure people use scratch x with a pc, im not 100% THOUGH. OHC is Optimum Hyper Compound - similar product to menzurna power gloss. OC is similar to Menzurna Intensive Polish. OP = optimum polish which is ismilar to your FPII Obvisouly, avid users will say there are differences, which ther certainly are, im just trying to give you a ballpark.



Your out of IP? Bummer, thats good stuff. Yeah, all the stuff you have may not be enough for your problem, except the scratch x, but im not familiar with that stuff . . .never used it.



have you tried the 3m medium compound on a yellow pad ? 3m has a good reputation on here, iv never used it so i wont speculate further than that.



sounds like you need to re-order some menzurna. i use the optimum line myself, but would love to have the menzurna line too, just dont have the money . . .



best of luck . . . try posting a thread on scratch x and the pc under machine polishing, or do some searching - but that is to easy to say - iv ran out of ideas for you concerning the products you currenlty have, due to lack of expierience with them.

I bet i could remove that with DACP and a cutting pad followed by #80 with a polishing pad.

Actually, I have some DACP as well, I'll give it a try tonight with the yellow pad. Correct me if I'm wrong but I don't think DACP is as aggressive as 3M medium cut or #4 Heavy cut is it? I tried DACP back to back with the 3M medium and the 3M hazed a lot more and more red paint was on the pad after once use.
 
even though its not as aggressive, it may remove it because you are not breaking down the #4 properly...try it out....figure out what works on a section then move to the rest of the car
 
Like what toyotaguy said, you probably arent/cant break/ing down #4 with your PC. But DACP you can for sure break down with your PC.



I would defiantely try DACP with a cutting pad. Make sure you follow up with a less aggressive combo to clean up the haze left by DACP and the cutting pad.

I'll try the DACP again. So after doing a section with DACP for a minute or so, wiping off, should I expect to see minimal or no swirl marks? I realize there will be hazing, that's fine. Or typically do I need to do a section more than once to get rid of these swirls?



Just curious, thanks again.
