Very impressive indeed I've never seen this process before it looks quite difficult to perform by hand.

We have been doing it for quite a while but it does takes some practice to achieve the desired results. Thanks for your comment.

This is awesome. I've thought about this before but I didn't think people actually did it.

We were using this on vintage cars 20 years ago.

Is there any advantage to pre-heating the material you're spraying. It doesn't appear that there was any pre-heat done?

What is the brand name of that tooling (gun)?

The process is called a cold spray method where the bond of the spray medium being twin wires one positive the other negative coming together to form a arc as it shorts. The spray hits the surface to form a mechanical bond. you can also use zinc coatings to combat corrosion

this looks like it could save thousands of dollars, what an impressive process.
