Because I live in a hirise condo with out access to a hose, I need to use the best automatic car wash I can find. When it gets above 40 degrees, I'll use one of the coin operated self service wash places. But its been cold, so Ive used one of the automatic places a couple of times this winter. You could see the results on the hood, and on the side panels where those rubber strips whip the paint into a frenzy. This weekend, I couldnt stand looking at teh scratches anymore, and since the weather is beginning to turn here (NY Metro area) so I decided to attack the surface damage that the winter hath wrought. After analzing the surface, I brought the following out to the car, after the automatic car wash had washed it clean: Porter CAble, Yellow Meguiars Polish pad, Orangey Meguiars Finishing pad, Cotton Terry removal bonnet, 3m FC Rubbing Compound, 3M Finesse It Finishing Material, and Blitz Carnauba.
Ive always taken real good care of the finish, so the only damage I had accumulated was that from the winter. Still, there were a number of clearcoat layer scratches and swirls from the car wash. I dont think I incurred any deep scratches this winter, so those that were there were the ones I had minimized as much as possible already over the years. Since its an entire winters's worth of damage, I deciced the Polishing pad with the FCRC was called for. I attacked all the horizontal surfaces first, starting at a speed of 4, but always jacking it up to a speed of 6, as the FCRC was worked in with the polishing pad. I would stop after a few minutes to remove the product and examine the results. I proceeded this way whereever I saw evidence of clearcoat scratching or swirls. I then moved on to the upper parts of the vertical panels. I finished off with some FI over some of the marks which remained.
When the car was in good shining condition, I applied the Blitz with the finishing pad, and removed it first with a MF towel, and followed up with a cotton terry bonnet on the pC.
Results were sensational. It looks like it had been kept in the garage all winter! It certainly feels good when you can effectively remove all the damage the season had introduced as though it never was there. Ive gotten myself to the point where I have 3 different regimens to use, depending on the seriousness of the damage.
LIGHT SWIRLMARKS
PC with SMR, FI, DACP, or FCRC in order of agressiveness with Polishing pad
TOUGHER MICROMARRING
PC with FCRC and Wool pad, or Cutting foam pad
TOUGHEST SCRATCHING
If PC wont do it, turn to ROTARY, and go through above chemicals and pad progressions.
I havent found a regular surface problem yet which hasnt been solved by following this regimen.
