I had used wool in the past and decided to try foam for the first time based on the posts I have seen on this forum.
Well, I just spent a bunch of money on foam pads, backup pads and the compound for the pads and I feel like I wasted the money.
I went back to wool after getting really p***-poor results with the foam.
Was using the white pads with Perfect-It II 05973 Rubbing Compound and the grey pad with Perfect-It III Trizact Machine Glaze.
I am doing a car with PPG Direct Gloss SS that I had color-sanded with 1200/1500/Trizact 3000.
Wool is working great using 3M Imperial Microfinishing first and 3M Finesse-It II next.
