I am looking for advice on whether or not its worth the cost and effort to soda blast (or crushed glass which some say is better). I have a 1974 transporter that has only light surface rust spots and one hole. It is going to be given a full respray and I want it to last a while. I have been quoted anything from $1000 to $1400 to have it done. Loooking at many of the resto sites many seem to do it. Worth it or not? Seems it would save a lot of time and dirty effort. Also if anyone has had it done a recommendation would be good.
