I am restoring a 62 Olds Starfire that has about 150 feet of stainless trim. I purchased the kit with the black, green and white compounds. Using black with the sisal wheel, green on a vented wheel, and white with a sewn wheel. I have been able to get a really good finish on pieces that had very fine scratches. The pieces with more or deeper scratches didn’t come out as well. After reading some posts here, it appears that I have not been agressive enough with the sandpaper, using 1500 wet/dry. The sisal wheel with the black is not getting all the scratches out. Since all the trim is 1/2" to 1" wide would an expander wheel with 400 sandpaper be too agressive? It’s gonna take forever to hand sand 150 feet of trim.
Thanks.
