Hector, I have one of the Badger "mini sandblaster's" I would NOT reccomend using this on plastic. I use to use mine for stripping the paint off of Brass Locomotives . It will take any detail you have right off (panel lines, ect.) or even make holes in the plastic. It is a siphon feed so turning down the pressure low enough will result in no pickup of the abrasive. They are marketed for etching glass, cleaning up metal toys and such. Jump up one colum to techniques , I have a Post on Stripping Paint ...
