Hi all,
I'm looking for some sand blasting advice. What media do you recommend, and how can I avoid warppage? What do you recommend to coat the sandblasted metal with? I purchased a 20lbs HF sand blaster and I'm planning on doing this myself |

Make sure you wear proper respirator.

Don't use sand or other hard material on body panels. It will warp and/or work-harden the sheet metal. Soda is a better blast media.
Blast media of any type will infiltrate every nook and cranny in your car. There are better, more gentler ways to remove paint - like paint stripper. Sherwood PS: for generic automotive questions like this, I'd source a broader source of information, like a body and paint forum. MHO. |

I would use soda to blast the body panels and sand for the floors and undercarriage. Sand could tend to warp body panels. With sand be prepared for a big mess.

From my own experience sand suks. I used aluminum silicate with a tarp under to collect the grit for reuse. You will need a good compressor, vary the pressure to avoid damage to the panels.
If you have some spare dollars use a professional shop that media blast with plastic beads which are far more gentle on panels, the shop can also spray primer directly onto the freshly blasted metal to stop oxidation. Soda (I have tried it) requires higher pressure and you will be surrounded in a thick fog of powder. For best results dry ice is excellent, I looked into when I renovated my 912 but is was too many $ |

Any source for plastic media? Amazon has some at $50 for 10 lbs. Sounds pricy. What about the bare metal. Anything I can do to prevent rust? |

I mostly use glass beads which can be had at HF at a decent price (remember coupon--they carry other media as well). I've discovered that it is a slow process when trying to remove the original paint (parts mostly) so a more agressive media would be better for larger areas. Hope you have a compressor with a decent CFM output or you will be frustrated.
Have fun, Keith |

Plastic is more expensive than other media but it can be reused/recycled many times... try these guy's http://compomat.com/acrylic-plastic-blast-media/

Use a good moisture separator or your blaster will clog up with clumps of media every 15 minutes. Very annoying. Put a fan blowing on your compressor to help with cooling if you are going to blast for more than 30 minutes a day.

The shop I sent my car to had it soda blasted and this is what it looked like when it came back to them.
They swear by this method. FWIW I have had cars sand blasted before. The finish was far rougher and there was sand everywhere forever.. |
