Wow seriously, I've tried finding the answer to this relentless without posting up a new thread that I knew nobody would reply in, lol, thank you so much for answering this.
I've used SSR's before but my buddy has them and I can always borrow them but I don't have any polish of my own and was really considering buying IP and FPII to use on a few family members cars that could use a good detail, mine included. The only thing I'm unsure of is using on Honda and Toyota paint which I guess is notoriously soft, not sure if the IP would be to much and maybe I should just use the FPII and an orange pad?
