Sonic Foam System - Combo Set 1/4" 3/8" 1/2" - 160 Pieces - 26" (Medium) air tools I use it to spot-treatThese are the tools I've decided to use at OGHQ, they have a nice quality to them with good ergonomics. They aren't intended to replace everything but there is a great variety of tools offered here. For the price, you cannot beat them vs something that's 2x or 3x the cost like Snap On.
