Default what is this problem (top coat damage)?

Hi all

I decided to give the Menzerna IP another go after my first attempts didn't seem to have any effect (to remove swirls). I put this down to harder than average paint. However, I thought if I gave it a bit more elbow grease for a bit longer I might have more luck.

On the surface ('scuse the pun) it does seem to have removed some of the swirls and on the bonnet and wings it is particularly good. But on the door panels there is now another defect - don't really know how to describe this so I have included an image.

Is this a result of the IP, and any ideas how to rectify it?

Thanks in advance
Nick

I have used the Menz ip several times. Initially I applied it by hand which was extremely hard work and often left smearing and milky patches as yours has.
To remove them I used 'quick detailing spray' which worked a treat.
I now apply the polish by machine and it was fantastic on the wife's Mini, removing some very visible scratches.

Looks like a bit of marring left by using the IP, it needs to be worked hard to get the best results, work on small area's max 18 inches square, work until all residue goes clear for best results.

Thanks chaps, I was wondering if it was marring. I use Megs quick detailing spray to remove the residues but this 'effect' is still visible in sun light. I think I might have let the IP get too dry on the door panels and this caused the problem.

Agreed, looks like marring - was the pad becoming clogged with product residue by this point? Once a pad gets clogged up, you can't break all the particles down properly, and the net result is typically marring. Try doing the affected areas again with a little less product and a clean pad, and focus on working it firmly until the residue has all but disappeared. Also, in warm weather keep the work area small, no larger than 12" x 12" square.

Yes it was starting to clog up. I'll follow this advise, thanks. BTW how damp should the pad be?

i always season my pads with a watered down spray of qd the when i'm polishing. then if/when the pad starts to clog, i run a tooth brush across the pad while the machine is running. this cleans it out without loosing the seasoning of the minimal polish and spritz.

Aha! i think this would have helped at the weekend when i had my first attempt at using a rotary polisher on my bros van, it has never been washed and the paint is almost chalky, after a couple of passes with the RD3.02 i then did a pass with the 85RD and it actually created a reflection! lol

Although it worked the pad didn't move across the surface as smoothly as i would have liked, but the condition of the paint probably didn't help!

keeping the surface slightly damp when using a rotary helps to get it gliding. also did you clay first? this should/would help a lot. what speeds where you working at and with what pads?

the chalky feel / look is oxidisation on the paint. sounds like you improved the paint condition a hell of a lot though.

No claying, juts had a play with the rotary, i dont know if the clay would have done much to the paintwork it was so bad!

Well my Silverline rotary polisher seems to run very slow on position 1, like i can stop it with my finger? so i had to go up to around 2.5 and this wasn't that fast but seemed to do the job!

Going to try the scoobs roof on Wednesday after a wash / clay.

My preference is to work with dry pads with Menzerna polishes, i.e. no prior spritz with QD or water at all - this is because Menzerna is so well lubricated anyway.

Thanks. Through trial and error I've just noted this myself. Getting much better results now .
