I can get the same results without buying a $300+++ kit. Those kits seem to have alot of stuff in them but you can get the same results with a 1/4 of whats in those kits.
You can get the same results with Sonus DAS/SFX kit and megs DACP #83 and megs speed glaze #80 or all 3 of the SFX polish line. So for ~$250 you can get the same exact results.
