I do have a air die grinder and really really use my blast cabinet. It's why I got a compressor. I don't paint. Just warning new guys of the pitfalls and other opportunities. Those who have been around for awhile have figured out all if this already. Just want beginners to not forget electric. Just a greasy spoon type post. It boils down to the number of trucks/cars you are going to do. Some will just do one and others will do 20 or have a business. I've done over 20.
All the comments and opinions are good food for thought. Keep them coming.
