Just had one done with soda last week and Lee is very correct about the rusted areas. I do however love the finish it leaves its very smooth and takes very little to get ready to paint. I also like how after the paint is removed you can see any original markings or metal fingerprints.

It was probably a note from the assembly line worker to his bookie, telling him the line on the 1969 Superbowl.

Thanks for the comments guys. The car has not been painted at all since 1976 and has no rust anywhere except the lower trunk pan, but I think you are right and I should blast the car while it is this far apart

I certainly don't want to redo the resto anytime soon

Thanks to your comments, I'm going with the shop that does the full resto routine...booked it today and should be in there by May at the latest. Thanks agian!

I did not read this thread in its entirety so if this is a repeat I am sorry.

I have always known "media" blasting as using plastic media to remove paint. It does not remove rust or grime/under coating. Simply paint, nothing else. "sand" or "glass" blasting to me, means using a highly abrasive material that removes all inhabitants down to bare metal. This is ideal for small parts but not really whole cars because of fear of warping the metal. I would tend to agree that "walnut shell" blasting would be the best route for a car. Not too aggressive but penetrates the metal and cleans the metal with full affects. Plastic Media is also very thick and coarse. Sand or glass is exactly that. Its very fine in consistancy.

Sand blasting:Absolute bear metal.

Media Blasting: You can still see the outline of the original AC Delco ink stamp on this oil canister from a '58 Fuelie Vette.

Hope this helps.
