More like how to wash so many cars you need to hire a helper. At our office park, when the mobile car washer decides to take a week off, people say "too bad Juan didn't stop by this week" =(
Like where the letterings were is a whiter than the rest of the truck? or there are still sticky residue?
My brother's white car had a ghost image of a dealer sticker. Turns out his white paint around the sticker is just really dirty. We clayed then used m80 and a finishing pad to turn it back...
+2 - I use it for 303 protectant on trims.
For tires, I just use a grout sponge. I hate applying this thick purple gel stuff. I tried paint brushes/foam applicators/towel. Went back to the sponge.
I have a 4 years old scratch-x that is very watery with chunks of white goo.
I'm tossing it into a brass tumbler tonight to see if it'll "homogenize" (idk if that's the correct term) again =)
Then again, my equally old m83/m80 are just fine.
There's a PPG dealer in SW that have some 3M & Meguiar's stuff. Foam pads, ultrafina, clays... no wax though. You can by p21s stuff (or ps100, i can't recall) at the Harley-Davidson dealer.
