I wish i took some pics of this job I did this weekend. Mean waterspots I had to do an estimate for the customer first , so I tried PB's PP on a spot and it worked . But then I tried it on the front fender where the sprinkler hit it the most and the PP didn't make a dent.
All sprinkler water isn't created equal . how long as it had a chance to set in?or bake in?
What worked best for me was using medium grade clay bar. I clayed it twice fairly aggressive and all of it didn't come out. So I used PC yellow pad w/ 2.5. on 6 with alot of pressure. If you have a rotary I'd use that . I spent 7 hrs buffing claying, buffing and sealing . It came out cherry except the water etched the bumpers and it wouldn't come out . The black framing and chrome moldings were the worst . I used DACP by hand .
Don't be afraid to charge accordingly . I got 265 plus 35 tip. I eaned all of it. I wish my wife knew how to give a massage..LOL
