just wanted to offer this tip. after i wash my blaster, i find that using a leaf blower works great to blow all the water off of it and out of all the tight spots.
Haha Nice one. There's some creative uses for a leaf blower aside from clearing leaves. If you've ever heard of the leaf blower turbo charger you'll know what I mean, if not, check youtube. Personally I use mine to clean my vacuum cleaner's air filter, works much better than compressed air.
Good time saver in a climate controlled garage, and I assume they use an electric blower, but being a guy who washes his cars out in the driveway I'm leery of blowing dust and debris at 400+ CFM on any gloss surface that I care about. Great for the scuffed up blasty though.
