One bad experience with sand or bead blasting is getting all the media cleaned
up after the job is done. No matter how hard you try, it always seems to keep
coming back... even after the car is finished. Also, blasting only gets the
exposed metal. Dipping get's it all, inside and out. Remember, Alpines rust from
the inside out. I've seen many "Rust free" Alpines that had areas of metal that
were paper thin. I've got one in my garage now that the DPO swore was a rust
free car. It even looked solid, until I started poking around. Anyhow, back to
blasting... One of the biggest concerns about blasting is the person doing the
job. If they don't know what they are doing, they can screw a car up very
quickly. I too had a BMW blasted prior to restoration. The guy used conventional
sand and warped most of the panels. It was a very expensive mistake! Regular
sand will get too hot. There are special medias designed just for automotive
work. Don't feel like you did something wrong by having your car blasted...
there are many ways to skin a cat! BUT, Jan and I both agree... from our
experience, that dipping is the only was to go. The body comes back VERY clean
and when the rusty areas are cut away to begin sheet metal repairs, you have
nice clean metal inside to work with that makes welding a pleasent job. I
believe dipping makes the whole job much easier in the long run. My 2 cents...
