When I got my body back from the sand blaster, they did a good job of blowing out the sand. The only place it took some more effort on was in the quarter panel pockets. My car was completely bolt free-stripped. You should consider putting tape and/or signs (spray can saying DON'T BLAST HERE!) on any areas that you don't want them to touch. Keep in mind the guy you explain it to that gives you the quote etc. is not going to do the work. It will be some minimum wage guy that may not really care so taping and signs are the way to go. My mistake was telling them to lightly dust the roof (inside). If I had to do it over again, I would use the same process except deal with the roof (inside) myself.

For a car you value, you need to strip to bare metal properly and without leaving chemicals behind. Aluminum oxide does not leave active chemicals behind. Soda remains chemically active until the reaction is spent.> > Soda blasting leaves a fine dust like flour throught out the car and the seams that remains chemically active. Soda attracts moisture and causes moisture to cling to metal where you can't clean it. Sure, soda might be good on a panel where you have access to scrub it off. But these cars are full of hems, seams, pinch welds and nooks & cranies this soda dust can never be cleared out of. It all retains moisture. That is why a box of Arm and Hammer soda clumps when it sits. Worse yet, it is chemically reactive. This chemical activity will cause continued corrosion and then paint failure later on. If you have ever examined a paint failure, it begins at a breach in the finish. The rust crawls under the finish for great distances. It lifts paint as it travels beneath the paint. Worse yet, the finish traps moisture that accelerates the rotting process. > > The more I rotate my project on the rotisserie, the more media that drifts out. Imagine this is a chemically reactive flour that you can't vacuum out of seams and that doesn't drift out as you move the project but remains trapped in seams and hems to cause continued corrosion and rusting. You might as well spray your car with Ford Maverick remover spray. > > You don't see Chip Foose sending cars out for "soda blasting". This is not a suited process for restoration work. It is a process for folks rushing a car through "restoration", tractors, or for the "buy it now" jackson acution while not attending to the defects that cause these cars to rot out later on. > > Larry> _________________________________________________________________ Discover the new Windows Vista http://search.msn.com/results.aspx?q=windows+vista&mkt=en-US&form=QBRE ------------------------------------------------------------------------ Submissions to Firebird-L: <[email protected]> Unsubscribe from Firebird-L: <[EMAIL PROTECTED]> Help: <http://FirstGenFirebird.org/firebird/Firebird-L.html> Classifieds: <http://FirstGenFirebird.org/ubb/> Owner Pictures: <http://FirstGenFirebird.org/show/> Donations: <http://FirstGenFirebird.org/store/cart.mv?999999> FGF Merchandise: <http://FirstGenFirebird.org/store>
