Sand Blasting

[vegas702]

I'm a newbie when it comes to everything on my FJ40, and now I want to start on the paint and body work.

I have removed small parts, and want to get started removing the old paint.

I may get access to a sand blaster (for the small parts), but am worried about pits in the metal.

Advice needed here.

check out the harbour freight blaster......not to bad for the price. Keeping the material dry along with the pot is a must .

material(media) has a lot to with it and pressure. You can use soda for real light duty stuff

Will sand blasting pit the metal?

i blasted all the parts shown with #80 aluminum oxide and they came out beautiful. If pits are a concern turn down the air pressure or increase the distance from the gun to the part.

If you use fine silica media and Low -100 psi pressure it's fine for blasting small stuff when your ready be sure to handle all blasted parts with cotton gloves oil in your hands can leave a oil residue then get to primer/sealer right away store away from any place they can rust even thru primer thats why sealer is important.... Brian I have a blast cabinet not being used call me ...

It's unlikely you're going to be able to pit the metal with the average home compressor. Mine makes 175 psi and runs on 220, I use number 3 sand, never had a problem. If there is rust on/under the surface, and you sandblast it away, yes, there'll be a pit. the rust was there and has to be addressed anyway, so not an issue. You'll likely have to sand the surface after sandblasting to give a factory type surface, unless you have infinitely more patience than I do and use a very light abrasive.
