sand blasting VS soda blasting

[Phoenixfire1989]

What is the difference in how it effects the metal..which is better..and does anyone know a price range in how much each cost?

For what part of the car? Sand is good for frames, brackets, suspension parts etc but a big no-no for body panels.

Well..i need the body redone..so yeah..body panels and such. I have some nice rot holes..and paint bubbles..and dents..dings..





And i'm showing these vents cause i need a crack in the firewall INSIDE them fixed. It's been leaking water onto my floor..


I wanna do the best restoration i can..unfortunately i'm gonna have to take it one step at a time. I can't afford to have everything done at once. I'm unsure how i'm gonna restore the body after i have the engine put back in it..cause i think it would have to be out of the car..

My vote goes to soda, for paint/cleaning purposes, it will not blast away rust. I recently bought THIS as I will be totally stripping my car. As for rust, grinding, sanding, and cutting will be needed. It also has a plus in having a rust-inhibiting protective coating.

Soda blasting +1

I have been reading that soda can cause paint adhesion problems down the road

Yup. Pretty sure you really have to neutralize the soda well or you can have issues.

Hot soap and water or some simple green is all you need to neutralize baking soda. The real key is scuffing the surface before you prime. The blasting leaves it too smooth for primer to bite in properly. I usually go over everything with some 80 grit paper first.
