Follow directions and they all work fine. I think it really comes down to "how long" and "how involved" you plan on being in your project. I do almost everything on my projects. I don't like upholstery, transmissions, or electrical. Doesn't mean I don't atempt to do them, just don't care for it. Its all really a great adventure, we all get there different ways. If you're in the business, you're like a guide, you go the way you know that works and is safe. if you're a "do it yourselfer", its a brand new trail. Try them all I say. Sand it, chemical it, srub it, soak it, sand blast it, media blast it, soda blast it, por-15 it, and when you find something that makes you smile....share it. lol. Its the Forum man, sometimes I try something and can't wait to complain or parise my efforts....whatever you do, it gonna be better than doing taxes or fixin the plumbing.
