Well, i finally got a chance to start the semi trucks I clean. I got the PP2 & some Polish with carnuba, White & orange vc Lake country pads. I am very happy with the PP2 & the polish! Looked great when I was done. Owner was very happy as well. The hood seems to get the most abuse, so it was the tuffest. Keep the rps low. No higher that 1400, backed down to 1000 to kinda put a little extra shine on it. Never used the orange pad. Main goal is to keep the paint clean & shiney. & swirll free. So far I didn't see any. Used a black pad I had for the polish. Really came out nice. Very nice. PP2 shined up the muffler cover & the stack really nice too. Took a hole 10 minutes by hand. I am very pleased with the products I bought & can't wait to do the rest of the trucks. There are 7 all together. & the BMW & Audi also. Thanks again!!!
