dustless blasting

[bluecoupe30!]

Plastic media should be a good choice if it does a good job of removing the paint and does not transfer to the metal. My company uses walnut shell for removing Aerospace coatings if we don't want to damage the substrate metal. The problem with walnut shell is it can leave an oily residue that interferes with adhesion. We have a process that removes the oily residue but it would be difficult to do on a vehicle.

This is interesting. I have thought a lot about walnut shell blasting as it is non toxic (like an untrained newbie could try it) and biodegradable. Thinking of doing some small parts at home. I think I have read other media need film cleaned off as well. So I am curious what chemical would remove anything left behind on walnut shell blasted surface. Anyone?

That may be true prior to use. After that it’s full of old paint and chemicals.

Great videos of Alex's project, thanks. Walnut shells eh, ? But I see , if you don't have a dedicated room and all the ancillary gear, perhaps it is better to get it into some shop that you trust, then just pickup when done.
