sandblasting - not my first rodeo!
Wow, it's amazing how juiced up people can get about a little thing like pushing sand particles at 100 mph!!! Gotta love this forum!! Thanks guys for being as passionate as I am to do things right!!
The only things I've been getting blasted are the heavy items like frame, brake shields and brackets. I specifically asked the guy to do the door edges and to just remove the worst scale at low pressure. The other items had come out great.
Thanks Randy for answering my real question about how to approach the problem. I'll try the disk, should be fine with that because there's really not much stretching. Just wanted to know if there were any tricks to finding the areas to concentrate on. If for some reason that doesn't work, I'll pull the doors off of the parts truck and go with those.
Makes me laugh at myself though, I'd rather spend the time to learn how to master the strectched metal (now that it's jacked up) than to just go pull those other doors!!
