So here we go. I did a friend's 4 door white Subaru... I didn't know it was THAT dirty... but after 8 hours of work (from inital wash to final wipe of Collinte 845), I was VERY happy with the results.
2 products stood out as being very effective in this case: TarX and Adapt.
Car regimen included a Dawn wash (the car had no lsp), TarX, re-wash, clay, re-wash with Meg's Gold, and then Buff&Shine orange foam pad with Adapt.
The car was filthy, tar specks everywhere and rust blooms everywhere on lower panels and bumpers!
TarX took care of the tar, with a little agitation for the bigger spots.
For the rust bloom, I had no Valuguard system, no IronX etc... I wasn't sure what to do. I had white Meg's clay and Mother's Yellow clay and they barely touched the rust (probably fine grade I guess).
I was ready to give up and said why not try Adapt on them... 2 passes later, no blooms left! I was very nicely surprised.
My experience with Adapt: easy to use, minimal to no dusting, applied medium pressure and finished well. I did encounter areas of the paint where there seemed to be some polish left on the paint after my passes that I had a hard time getting off... I am not sure if it was the infamous Subaru soft paint, the pad being too gunked up (yes I cleaned them often), of a technique issue (I did 2 passes on speed 5 using HD DA, medium pressure, then 1 or 2 passes on 3, no pressure other than weight of DA).
I did notice that Adapt worked best with clean pads and although I used 3 pads to do the entire car (minus roof), It would have been better with 4 pads.
Long story short, Adapt rocks, TarX rocks and I need to buy more pads!
Pics below are from cell, sorry... it should give you an idea of before and after.
Cheers!
