I am either going to sandblast or walnut blast the shell next week.

I have heard that you have to put silicone on any threaded holes, or the sandblasting will eat the threads. Is that true?

What other heads up tips are there for sandblasting?

Go to Lowes or Depot and buy a slection of rubber plugs to fit your threaded holes. Eastwood sells silicon plugs to fill threaded holes too. I would not use silicon sealant to fill the holes.

Wear a respirator!

I've blasted soda and walnut shells on a few cars, the Baur included. A simple way is to roll up some electrical tape and screw it in. I've not had one come out on me yet.

Bruce is right. Silicone would be a less than stellar idea.

Very, very true when you are 6'5" like me.

There will be sand EVERYWHERE- sunroof mechanism, wiper transmission, window regulators, etc. I highly recommend (if you haven't done this already) that anything that isn't welded on be removed. Ask me how I found out about this...

What are you doing about the tar and sound dampening on the floor, firewall and exterior panels? I recently read about using dry ice and the results sounded pretty impressive. Harden the stuff with the dry ice then just chip it off.

is you are using a sanblaster so strong that is eats the treads away on nuts then its far to hard, i have sandblasted nuts on panels and they are fine, you must be using a very heavy sandblaster to actually start eating the steel, you dont need a powerful sandblast like this, it will just damage the shell.

You might find it easier to have someone strip it for you- usually costs between 3 and 6 hundred dollars to do a whole car.
