well true to my nature i just cant leave anything alone. spent the weekend replumbing my blasting hopper . just did not like the way it was set up from the factory. it has a pinch valve on it that takes about 60lbs to close. which in turn put 60 lbs into the hopper. well after a few beers and a while of pondering i got it like i wanted. i can dial this sucker down to 10lbs now and still close the valve. it will work really well now at 20 to 30 lbs at the nozzle . blasting corvettes at 60+ was a little scary and troublesome . using type6 acrylic and corn cob at 30 will be nice. i can peel it one layer at a time. i should be able to take even the factory primer off . will be nice to be able to blast then wash with dawn then straight to epoxy after it drys. cuts out a lot of sanding which is fine by me

have you used soda?
I'm a little scared of using just about any media on the SMC used in C5's
I'm talking about single panel off the car blasting I know that not removing the soda completly is bad.

no soda in my shop. i researched for a year before investing in the blasting business. soda was never intended for use on cars. it is used primarily in the food industry and industrial cleaning. was also used for grafiti removal. if done exactly right it may be ok but i will not chance any kind of acid or caustic materials. redoing one of these cars is not an option for me. i have learned over the past 40 years that solvents are the leading cause of paint failures. in talking with barry at spi the #1 call he gets is just about always some kind of metal prep or using lacquer thinner to wash with. he fields over a 100 calls a week sometimes so i figure he knows what he's doing. he mixes the materials so i go by his rules. to second guess the mfg is just asking for it. i have epoxy and urethane on my jobs. nothing else.
