Eastwood’s 30% off sale couldn’t have come at a better time! I was planning to get some buffs and compounds to give it a try and now it’s a no-brainer. I’m looking at the “Stainless and Steel Buffing Kit” which includes Sisal, Spiral, and loose section buffs as well as three tubes of Emery, Stainless, and White Rouge. There is also a 4 piece set which includes a Canton buff. Since I’m basically just doing car parts, do I need the Canton buff? Also, how are these compound tubes to work with? Are bars better? Recomendations on which size buffs?
