Soda blasting heat build up
So I'm just wondering if people know how much heat soda blasting generates in body panels?
Reason I ask is I want to keep the exterior paint in it's patina'd look for now but get the interior looking nice. Thing is, when I come to paint
the exterior I don't want the good paint on any of the interior faces getting damaged by heat build up from the soda blasting on the exterior.
You know, places like the inside of the inner rear wing or interior of the roof or door panels.
Cheers

heat, virtually none. even sandblasting don't make much heat, its more the shot peening effect that warps it. I can't imagine fine bicarb soda shot
peening anything so I recon its safe.
I have talked to people about it before and no one I asked experienced any heat or warping.
its safe enough apparently to blast with windows, seals and trims still on the car as it suppose to only take of soft material like paint and
contamination.
I used to do a lot of sandblasting at my old work back in the day and there wasn't never any heat involved, I once warped an aluminum panel instantly
and it warped out by more than an inch over 30cm of panel but there was no heat or warmth involved. The shot peening effect did that.

So you reckon it won't affect the good paint on the other side of the panel?
If so then that makes things so much easier for me

Soda Blasting
HI,
I've had a bit of stuff soda blasted, the only parts i;'ve had issues with are doors, even soda blasting can distort door panels if there is a lot
of paint to remove i.e. doors been painted several times or has a lot of filler to remove. Just take the safe route and blast the whole frame around
the door inside and out leavingthe flat surface and remove the paint by hand with paint remover.

hi
I had my car done, it comes down to how good the operator is whether you have distortion or not.

Well as I said I'm not getting the whole car done at once but doing the interior first and then the exterior when time and money permit.
But I can only do the interior if I know that when I come to blast the exterior any heat doesn't affect the new paint on the interior.
If blast the exterior causes too much heat so that the interior paint lifts, burns or bubbles then I'll just have to put up with the interior looking
like poop for the next few years.
I'd much rather have somewhere nice to sit whilst driving yet not fussed if the exterior looks shabby
So hence me asking if soda blasting causes heat problems that would affect paint on the other side of a panel being blasted

I would say the doors were more than likely distorted from minor parking lot dings, hence the multiple paint layers and filler.
I know on my current project my doors have distortion and it only been repainted once (only on 3 of them). I am block sanding it and that shows up
distortions pretty well. all the other panels are pretty straight so its the multiple little dings that has done it.

I highly doubt it, even regular blasting never did such thing when I used to blast things in the large cabinet at my old work.

Cool. So just to make sure I've read your reply correctly, you are saying that the blasting will not affect the paint on the opposite side of the
panel being blasted?
This will be good news to me
