I have had this conversation with a few people I more or less respect, and have gotten several different answers, and am looking for some other opinions... Basically, I have been sanding the rust and paint off my frame (and numerous other parts), with the idea that when I send the stuff off to the blaster, it will reduce the amount of time to completion, thus reducing the final cost. The answers I have gotten fall between: "Why don't you just do all the sanding yourself" to, "You're wasting your time, since they are going to go over the whole thing anyway" Usually the first answer comes from the least affluent of my acquaintances, and the latter from the more affluent (border line goldchainer's). As I said, cost is a factor, I can afford it, but would rather put some elbow grease in and save myself probably hundreds of dollars, and getting into some of the nooks and crannies effectively would be nigh on impossible... Seems to me that even if they do go over the whole thing it would still take less time if all they are doing is blasting out paint from pitting in the metal, rather than starting with pure rust/paint. One suggestion was to call the blaster and ask them, but what business owner in his right mind would suggest you reduce the amount of work and coinciding profit for them? Opinions from the gallery?
