My panel shop wants to dip not soda because he says you cant get all the powder residue out and it goes everywhere when you start spraying. On the other hand the concern people have is that if you dip you take paint off in places you cant get to too put it back on. In the end I will just have to decide and go with it and I will go with what my panel shop wants because he is the one that has to do the work and probably wont do it if I choose the other way. |

I have always used paintstripper. It is slow but a lot cheaper and I feel like I've actually contributed to the effort. Re "Flute's" comments: whatever method you choose, use cavity wax or fish oil once complete. |

Exactly. Especially if the panel beater/spray painter has dealt with the blaster in the past and they understand each other's needs. |

I usually use paint stripper first and then have the rust blasted and the body primed so it doesn't rust while repairing the rust. |

Nic, I have used soda blasting in the past. The finish is excellent but does require careful preparation before paint. I did not have trouble with dust, one advantage of soda blasting is they rinse the car with water when finished. Next time round I will use hydro blasting which is a form of when blasting with crushed glass, it's very efficient and gives an excellent finish . Dipping is fine for bolt on panels but I'd never do a whole body. It is far too easy for it to go bad if the people doing the dipping don't neutralise the metal properly. You can end up starting corrosion everywhere you can't paint. |

Zactly Lindsey...if they don't know what to do to completely flush or purge the acid it can cause problems... A little soda media floating about is likely to be less destructive... |

I've heard bad things about both blasting and acid dip. Blasting never stops grit from appearing from hidden areas. Acid has seepage from seems etc. The places that do soda and then undercoat seem to be the best option. They wash and dry the car removing most of the blast then etch prime in water proof 2 pack. |

The key to success is to prevent any oxidization of the bare metal from the time the protection is removed until the application of the new protection. The window between raw metal to recoating should be as short as humanly possible and don't introduce anything that will start the oxidization process. |

Wash car 40 grit on sander to scuff through paint. 3 scratches per square inch is fine Wipe clean Apply paint stripper then cover with grease proof paper. Wait ......... Adjust wait on temperature Lift corner of grease proof paper and apply scraper, like scraping off a sticker, peel and scrape. Clean |
