Re: [Classic Mustang] Media Blasting

Hi Phil,

I never heard anyone tell me sand blasting can warp metal - but... I suppose it could; sanding causes friction and friction causes heat.

I was always told to use glass bead media because it was gentle (compared to other abrasives: aluminum oxide, carborundum) and that soda or walnut shells could also be used even on material you'd never consider appropriate for sand.  On that cowl panel - sandblast away without any worry.

HOWEVER ... never, EVER try and sandblast inside anyplace other a room (or box) designed for it because the stuff will go absolutely EVERYWHERE.  DAMHIKT! 

I did the whole front end clip of my car before I switched to paste stripper.  And to this day, I swear that is why I'm still getting sand blown out of my air conditioner... and its been 29 years (!) since I sandblasted my pony (inside the third bay at a filling station I USED to work at.) Man... there was sand 3 bays away, on the top shelf of the two-story work space. It was kind of pretty in a way - it had this a 'snow white' sort of thing going my.  It was built up on the fan belts, lining the walls, the shelves, loaded with air and oil filters, even the tires in the back room weren't immune to the 'media' touch. 

Oh, I was so in dutch with the owner, too  :-)  To call him 'Grumpy' just wouldn't do it any justice either.   And as a working filling station (in the day), grease covered a lot of things.  And where there is grease... sand sticks.  It was an awesome sight...  good thing I graduated and moved out of state, me thinks.

Michael, I have used sand to strip my engine compartment.  It was a long tedious task, and turned out great, and with sand I could sweep it up, sift it and reuse it.  What I could not sweep up, merely went into the ground.  Lots of sand here in NJ.  I am reluctant to blast in the garage, as I don't want a lot of dust in there.  I just purchased a used cowl, and the previous owner used glass bead, but did not get all the area around the grill to bare metal before they primed.  My friend the professional painter made the comment about sand and heat.  I checked out Eastwoods for different blasters, but trying to get opinions from others before I buy.  Phil
