Can I sand blast my doors or will they warp?

There is a guy up the road from me who has a NICE sandblaster. He blasted all my suspension stuff for $20 and it looked brand new. I was wondering if I can safely blast my doors inside and out? The guy says he has blasted cars before, including an old model T. Think blasting will warp the doors all to crap?

Thanks

 

I don't see any reason why blasting them would cause them to warp...

 

They absolutely WILL warp. Sandblasting creates a tremendous amount of heat. I have personally done it and have even paid a so called professional to do it after he convinced me he wouldn't warp them. Doors, hoods, and decklids are the hardest parts to blast without warping. Fenders and qtr panels seem to do much better.

 

Yeah, they will warp.

 

What about glass-bead blasting?...

 

Dang. Oh well, looks like I have to do it the labor intensive way. On that note, how easy is it to warp a panel using a DA sander? I did some sanding today and noticed that alot of heat was being put into the steel. I wasnt holding the sander in one spot either, I do know better than that. I was moving it around at a pretty good rate.

Thanks

 

Media blasting or walnut shell blasting is the way to go on doors, hoods and stuff like that. I have sandblasted many panels in my life and never warped anything. That is me, I have seen tons of stuff warped by so called pros. Less heat with media blasting, but still if an idiot is doing the work, watch out. Yes, you can warp a panel with a DA, seen it done. Just keep moving and you wont have a problem

I would sand blast the inside, the textured part and the jamb part. On the outside, I would start with a 8 inch grinder with 80 grit to get the paint off, then DA sand it with 80 grit, and 120 grit, then a quick 240 grit, to eliminate the 80 grit grinding scratches. When grinding, BE CAREFUL of the body lines, its easy to mess it up, keep the grinder on the lowest setting possible, I use a Makita, and it is nice to have variable speed at the trigger. You also could start with a mudhog with 80 grit. I know there may be different ideas on this but this is what I've always done.

 

A grinder? Wow. I doubt I could take a grinder to it without taking off too much material. The DA takes the paint off super fast, so I think I will stick with it, but I did want to get the inside of the doors blasted out due to some rust in there. I cant reach in there with a DA sander, and Im not sure if I could get any chemical stripper completely cleaned out if I used them.

 

That's very observant of you, but I did ask about it...

 

You can sandblast a old Model t because the metal - twice as thick as maverick metal. I would use chemical strippers. DA can warp and you take off too much metal.

 

Now, now. Everyone be nice

 

I agree with the previous suggestion. If you are trying to get paint off, try
aircraft stripper. USE A MASK- it's toxic.

How about getting the chemicals off so they dont cause the primer/paint to lift? How difficult is it?

Thanks
