HELP! Hard Audi Paint or bad techniques/products?

[vkamnyev]

Hi All! I haven’t made too many posts in this forum, but have followed several threads on here. I’m an enthusiast detailer and have done several light machine polishes and ceramic coating applications and have been very pleased with results.
Well, just recently my lovely wife decided to side swipe my 2018 black mythos A4 while backing out of the driveway. Pictures of the damage below. Immediately after, I got my porter cable out and used M105 with orange pad followed my menzerna3800 on a black pad. A week later, took the car to a local PDR shop and they performed their magic.
After i picked up the car, I noticed much heavier scratches that I didn’t see after I did the polishing. So there I went again with M105 on orange pad and menzerna3800 on black pad. Everything looked great and I thought I took care of the scratches. Several days went by and the car accumulated some dust and I can now see these scratches again - it’s like I didn’t even compound or polish it. HELP!! Finger nail doesn’t seem to catch on the scratches so that’s a good sign but I can’t get these out. What am I doing wrong? Should I get a microfiber cutting disk and try that? Any other techniques or products I should try? I appreciate any input and suggestions on how to get rid of these.

Hey man! From my understanding if the paint gets too hot it will swell. This makes it harder to cut and makes it appear that the imperfections have been removed, however, when it cools off they will reappear. I suggest cutting at a lower speed on your PC and doing less passes to avoid overheating the panel. Meguiars microfiber cutting discs is a great option for a more aggressive cut. You can even swap out M105 with M101 if you still aren't getting the results you are looking for.

I'm in Dublin, Ohio so about an Hour to just over from your place. If you're in Columbus anytime just hit me up, I'll look at it and take care of it. Cars & Coffee is on tomorrow, Saturday at Lenox near OSU Campus so if you make the trip for that, I'm 15 mins north of there. Happy to help. I'll PM you too. I have an Infiniti SUV I just finished up and tomorrow I have new Tesla coming.

Thanks! It’s probably worth a try with a MF pad- need to get one. Thanks for the suggestions!

Didn’t realize you guys had cars and coffee every Saturday - that’s awesome! Ours is every other Saturday. Would love to come out but will have to be another Saturday - maybe next week.

Cool. PM me if you head up. I'm usually detailing a vehicle thus I miss them but occasionally I take a weekend off or move a customer to Sunday.

Makita with a wool pad and M3 Cutting Compound (Step 1). Follow that with Makita Wool and Presta 2-Step. Then go back to the PC and foam for the Swirl Hider, Glaze, Wax.

Note the Megs products do NOT like the Makita and Wool! Megs 105/205 are for foam only.

... At worst PC with foam backer and 2000/3000 grit, but I hate to cut clear if you don't have to.

Does the wool pad work better than foam with 3M cutting compound? I used a foam pad last weekend and still have scratches from previous owner's automatic car washes.

m100 on a MF pad followed by m205 on a MF pad. DONE. If the paint is getting too hot, you need to change the pad. It takes a lot for the surface to get hot with a DA, even with a rotary my paint stays pretty cool to touch and Im always using the backside of my hand to feel the temp of the paint while polishing.
