thanks a lot for the info... I have the porter cable da and I use the meguiars 105 and 205 and then meguiars 26 sealant then yellow wax 21.. my father in laws red truck sits outside year round and his paint looks like the one above... I tried the yellow foam and the 105 and although it took a lot of the deeps scratches out.. you still can see them.. I followed up with the 205 and got a nice shine but the scratches still bother me... I might have to try the above products.... ...I didn't know if you were using the wool or micro fiber pads? again thanks for the info....
