special equipment for soda blasting?

[jackag91]

Next month I should be able to take the car to San Anotonio to my buddy's shop. He has the space and said that he is fine with me blasting the car there.

Can I just hook up his sand blaster and use soda or do I need to buy some kind of special equipment to do it?

Also, will it take off the undercoating or is that something I am going to have to by hand?

I'm sure somebody with more experience in the matter will chime in, but I believe you need a special blaster for using soda. In a standard sand blaster the soda will clog up the machine very quickly.

Thanks, I was afraid of that.

I guess I will have to get some quotes.

The guys I use all have special use mobile soda blast machines. They can come to your house if you want.

I have mentioned in previous posts that since I've started using soda blasters I wouldn't use anything else - great process - does not warp or damage the metal in any way.

Go to Google type in soda blast and your state or town and you should get some hits.

did you have to strip off the undercoat or did the soda blasting take car of that?

 

[zahnej]

Can't give you an answer on that. The parts and car I used this process on did not have undercoating. Best bet is to ask the blaster when you locate one. I know they have different grades of media and the fine stuff will not etch rubber, chrome or glass - the panel looks like the day it was stamped at the factory.

Yep, even the most aggressive media has a difficult if not impossible time removing the undercoat without damaging the surrounding metal. The problem is as it is blasted it heats up and softens then absorbs the media being shot at it. You will need to remove it. There are several threads on this forum with recommendations from those of us who have done it.

here is an email I got from a guy that will come out to your place and do it.

How does this sound?

A good ball park estimate for blasting an entire is around $1500. Now that is for a full size car, so of coarse a triumph tr6 should be less. Probably somewhere between $800 to $1000, it all depends on the time it takes to blast the car.

Yes Soda Blasting will remove undercoating, body filler and everything except rust. I use a fine crushed glass to take care of any rust you might have.

Hopefully this answers your questions, if you have any more or would like to schedule a time to blast the car, call or email me.

Thanks for the tips about soda blasting. But your to late,I already plugged up my machine last year with it.....what fun.

I have an excellent way to remove undercoating,but its stupid and dangerous.... but it works great.

If it was 1969 I'd tell ya, but it's 2007 and everybody is safety/health conscious and litigious to boot.

Hows that for no help at all.

Gas, a match and a puddy knife?

jackag91,

The price seems a little high. In my area - Virginia - the guys get between $600 and $1000 for a car, but thats taking it to them.

Dry ice and a rubber mallet works pretty decently.

(Slapping my head) I never thought of that.

Jack, I've had the undercoat fall off in pie plate size chunks using this method.

I just waited for a minus 25 day here in the great whit north and saved the cost of the dry ice /bcforum/images/%%GRAEMLIN_URL%%/smile.gif I still had to use some solvents in the areas where it was not thick enough to flake off.

I can't even imagine living like that. I start getting whiny when it gets below 40.
