I am not new to detailing, but this car is giving me fits. It's a black 2005 Porsche 911 Carrera S.

I was excited to try out the M105/205 combo, but I am not sure what I am doing wrong. After using the M105 with a yellow pad on my Flex, the paint is very rough looking. I was expecting it to finish down more like a polish.

Should I be using a white or orange pad instead? Or is the yellow fine for M105 with a flex, and the M205 with a white pad as the next step should take care of the haze and overall rough look?

Under normal light, it looks ok, but with the Brinkman, it's a mess!
Help...
 
Of course its a mess .. yellow pad is very aggressive thus the result.

Which Flex are you using, 3401 or PE14?

As you are probably not very experienced in detailing I'd suggest you start with Ultimate Compound (not M105) and white pad, and see how you go. M105 is very demanding compound, Ultimate Compound is not.

Keep us posted!

OK, well, I did a round of M105 with a white pad, and it's still quite a mess. Hit it with M205/ white pad and it's better. Still not perfect.

Perhaps another round of M205/ white?

This has been a frustrating detail.

I am not new to detailing, just new to these products. My go-to has always been the Menzerna line, which I always loved. Wanted to try the 105/205 combo, and I'm not sure I'll go with it again...
 
Yes i have detailed a few porsche's at a dealer i worked for, the paint is SUPPER soft. I used a grey ccs lc pad, with menzerna P083Q. I tryed the 105/205 as well on it, did not work at all for me.

Goodluck.
 
Everythings looks awesome until I hit it with the Brinkman. Then I see Micro-maring, really very fine. Nothing is getting rid of it!
UGH
:buffing:
 
I ran into a similar problem on a black 07 wrx sti. Soft paint can be so hard to finish down correctly. I've found that lower speed helps.

That yellow pad was probably just a little too aggressive.

I personally would probably have used an orange pad and rotary to start, then a white pad, 205 and rotary. I would most likely finish with a white or gray pad and 205 on the DA.

4500 should get rid of the micro marring. Have you tried it yet?
 
Has anyone tried the Optimum Final Polish in situations like these??

If you have Menz 4000 or better yet 4500 use those with a softer pad. Problem should be fixed.

+1

4500 on a finishing pad like red, blue grey etc will get rid of it. I have ran into similar problems like this... For this reason I only trust Menz polishes now
 
Plus one for SF4500 when finishing off soft paint after 105/205 combo. Hasn't failed me yet. In most cases my goto pad is a LC HT crimson, also try diminishing pressure the last few section passes. Hope it all works out for you.
 
Another vote for the 4500/85RD. I had a Berlina Black Honda S2000. To date, it has had the softest paint I've touched. I went after it with the M105/205 and got ridiculous marring. I backed off to my softest pad and M105 and finished off with the 85RD on a red pad. That did the trick.

I know this is not much consolation...
But by your stating: "I am not new to detailing"...
Implies (to me) that you know that by doing a Test-Spot surely would have been a 'best-practice'
in determining the products/tools/chemicals/accessories for this project.

(I may be wrong...But it appears you did not perform said "Test-Spot", before compounding the entire vehicle.)

Since you've also stated: "My go-to has always been the Menzerna line, which I always loved"...

-Then I concur with what smack (Mike) has suggested in his below post...With one caveat:
Just keep in mind the amount of paint that's already been removed...

BTW...I'll suggest otherwise to this sentiment of yours:
"105/205 combo, and I'm not sure I'll go with it again"...

These are excellent products!!
Just start-off with the: "least aggressives"...while performing the requisite "Test-Spot"

:)

Of course this is the test spot I am referring to, I'm no dummy:dblthumb2:
I'll try a few combinations out tonight and report back.
 
M205 on a soft finishing pad, slow down your speed on a reg da. I do a lot of Porsche and this works for me
