Terrified!

Hi,



Have lurked around the site for about a year and would classify myself as having enough knowledge to be dangerous and not enough to boldly go after my paint damage.



Recent purchase of a black car has pushed me to getting the PC 7424 and a collection of pads and products.



I purchased a very low mile, current year car that went through one winter with its previous owner (a BMW Executive). Clearly the guy didn't have a garage and wasn't too concerned about the paint. There are snow brush scratches everywhere. The fact that the car is black makes it infinately worse.



My first run at it I started with the Sonus Polish that came with the PC in the Autopia kit (A great Value BTW). I used the PC on 3 with the poliching pad.



The polish cleaned up the swirl marks a bit but really didn't put a dent in the scratches.



Next I tried some Zymol cleaner wax (based on previous good experience). It helped a bit but the deeper scratches are still there. I again used the PC but on 2 with the #1 pad.



In the meantime some j@ck@$$ decided that my car was too nice and used a pen knife to cut the leading edge of the hood in an x pattern above each set of headlights.



So knowing that the products I have aren't going to address the scratches much less the cuts, I went and bought some McGuire's Medium Cut Polish. But I'm afraid to use it as it is pretty far up the abrasive scale (7 out of 10) and I don't want to trash my paint further. I've hand worked the cuts and they are not as noticeable but I don't think they'll ever go away.



Any advice as to whether I should use a harder pad or softer one, what speed and how long to work the product? The car is scratched now but I certainly don't want to make it worse.



Another thing I've noticed is that I'm getting fine scratches from my microfibre towels as well between polishing and waxing. Too much product maybe?



This car is going to drive me nuts. I'm feeling I should have held out for a grey one.

Is there any way you can post some pics, so that the scratches can be viewed ? also did you see how the scratches respond to the fingernail test? if they catch tour fingernail they are deep and can be lessened but not removed. if they are not felt you may stand a chance. I always start with the least agressive product and pad. you can try jacking up the speed and slowing your hand speed down to like an inch per second over a 2x2 area.
 
I'm sorry to say but if those "deeper" scratches can be felt with your fingertip, you won't be able to take it out with a PC or Rotary. It will require a repaint.

Do yourself a favor and quit using polishes on speed 2-3. It won't do anything. Bump it up to 5 or 6 when using any polish. Particularly if you go up to an aggressive polish, you won't be accomplishing anything without using it on higher speed.



I think the reason you're getting scratches from your MF towels is because you're wiping off polish that hasn't been broken down. You're using the PC on low speed, which isn't able to break down the polish adequately. Then you wipe abrasives across the paint, and scratches appear.
 
Sound like a job that requires a rotary. Even pumping up the PC to 5 or 6 will not produce enough work to eliminate the majority of your described blemishes.

Black can be a constant pain, but with the right tools can be made to look extremely good. :xyxthumbs
 
Thanks all of you for the input. The new "ëyebrows" are probably going to require paint.



I once used a cheapo rotary with cheapo product and burmed the paint a bit (it was a 75 BMW 2002 so even burnt paint was better than what was there before). My investment in this car and the products and polisher are much higher thus the concern with screwing up.



I'll post some before and after picks once I can set aside a day to do the whole car.
 
With the PC, you won't be able to burn your paint, so don't worry about repeating what happened to you with the rotary. If you are going to get the scratches repainted, why not try touchup paint and then buff it down to the same level to see if it hides the scratches? If it doesn't work, then you can repaint. Good to learn too. :)
