Hello fellow nerd, lol. I'm the same way, man. I must have a zillion "how to" videos about every subject known to man. Check out
www.smartflix.com cool sight with tons of videos. Here's a few tips I've learned when I used to work out of my garage. If your budget is limited, then start small with a 60 gallon compressor and a couple cheap guns, just to get your feet wet. You should be able to find some deals on craigslist. By the way, most compressors run on 220. Make sure your garage is equiped. Next, you'll want to snag some visqueen(sp?) or some type of plastic sheeting from Home Depot to either set up a small booth or cover the rest of the stuff in your garage. Overspray gets into places you never thought of, so protect your stuff. Duct tape works well to seal up the plastic. Lighting is important. If you can hang a couple of extra flourescents, that would be helpful. At the very least, a halogen on a stand will work. You'll just have to drag it around with you. Box fans with some a/c filters taped over them work well to draw out fumes. Make sure nothing important is parked in your driveway while painting. Complaining neighbors will shut you down in a hurry. Take steps to insure no overspray is fogging up your neighbors houses and don't run your compressor at night. A small cabinet filled with masking tape, sanding blocks, sand paper and other necessities will be helpful. Try to keep everything in one spot. Paint shops can get messy real quick. Most importantly is to remember: this is your garage, not a full blown custom shop. Keep your projects small and managable. Nothing is worse than having a car sitting in your garage for a month cause you took on more than you could chew. I've done it and it sucks!!
