sandblasting help
Hi. What would be the best way to sandblast large peices of sheet metal, say a cab. My sandblaster pits the metal when I am sandblasting something, but i have this great orbital sander that makeks the metal as smooth as a baby's bottom. Anyway, it took me a month and a half just to sandblast my driver side door(which turned out really good after i primered it, or would it be primed it?)so how hard would it be to sandblast the cab? I want to take it to bare metal, as witht the rest of the truck. is there any other alternative that is reasonable in price and quality? I can get sand anywhere, but i really dont want the sand in my truck barn. Any help is greatly appreciated.

Sandblasting can Warp sheet metal.
You would be better off paying for Bead Blasting or just sand it down.
Try the *Bodywork* Forum, that's where the Body shop guy's hang out.

There's been alot of discussions already about sandblasting in the Bodywork forum. Do a search in that forum and you may also want to search for "dipping" and dipping alternatives. Professional dipping is quite expensive, but I recall reading various techniques awhile back in the bodywork forum. I've done all our sandblasting and although it is messy, I love the results. The length of time it took you to do a door does seem waaaay too long.
If you still have questions after looking at all the info that's already there, post 'em there and you'll get more help than you'll know what to do with.

Be carefull with that sand blasting it can really warp the metal. I had all the paint removed from my 68 corvette last year. It cost me $800.00 for the complete car . The body was stripped clean. The guy that did mine uses glass bead which is a lot easier on the car than sand.
There is a local company that also does acid dipping and e-coating. The only trouble with way is that the acid removes all bondo and sealer.

I haven't found the sandblasting at all warping to our truck. Of course, I'm using one of the small pressure units from sears. I started out with a siphon unit but was eating up too many tips.
I have used an industrial blaster in the past and wouldn't recommend it for do-it-yourselfers. It would definately warp the metal.
As for the safety part - Along with wearing the hood, I wear a mask, long pants, long sleeves and set up a work area that is well ventilated.

Try media (i.e. Walnut shells, plastic beads.....) they work real well. I used to paint Aircraft for the Air Force, and that is what we used to strip small parts. Worked real well and if you have the pressure setting correct it will not hurt the metal......
Thanks

There is also a process called soda blasting.. it's actually a wet blast...water and soda which leaves a nice etched finish on the metal... no heat... and no bondo... you have to rinse it down after the blast with vinegar but it's worth the time and trouble.. check with a commercial paint company for someone who does it... a painter who does industrial painting... I did my '53 and was very pleased..

Hi, I know there are a number of materials you can use in a sandblaster. Furniture companies use wall nut crushed shell powder and you could use very fine sand or eaven baking soda works on some materials. Good luck Colin

Keep in mind if you are using a blaster PLEASE always wear a good mask. I blasted for many years when in high school and even with a good mask I still feel like I'm spitting sand out and that was 20 years ago. When you go to your local lumber store and buy sand for a blaster you are buying silica sand. Sand blasting causes silicosis (a lung disease caused by the inhaling of silica particles)even a little exsposure is not good for your lungs.

on my 54 panel project I rented a large blaster and did the frame,door jambs, underside , inner fenders ,body seams , and the like but stayed away from large areas of flat metal.And used a heat gun and razor blade for them.Take odie780S advice and use a mask when blasting.
