About to start blasting my car body.... tips please ?

[rcx132]

Hey all.

I've read the forum how-to's, so I think I know how to start, but any last minute tips are welcome.

I've got a totally stripped down 4x4 body. All the rust that I could find by poking around has been cut out and re-welded, but there's areas of surface rust which I can't reach with sandpaper etc. The rust in these areas doesn't look like it has penetrated the metal, looks like just needs rust removing and painting.

So the plan is to blast those areas. They only account for a few percent of the cars surface area. Virtually none of the areas are on exterior bodywork except a few spots on sills and roof.

I've bought super fine grade crushed glass and I have a pressure pot blaster, 3.5mm tungsten tip, and 32 CFM compressor pair.

I was going to roll the body out the garage and make a start next week...

So wife decided to go out, so got some extra garage time to pusht he car out and start some blasting. All went well, goes quick and not noticeable heat being generated. The primer doesn't come off easy but I'm only interested in getting off the rust and roughening inaccess bits with the blaster. I reckon a day to get it all done once I've removed all the seam sealer and sanded down the accessible panels.
