I can really recommend it! When i work on new cars it is forbidden to use common Mig wire. It ruining the steel so it starts to rust and on the boron steel parts in frame beams it cracks and destroy the steels capacity !
You have to use a puls Mig and argon gas with this wire!
The wire is called Cu Si3
I used it on all the body seams on my Pantera to get them water proof and strong you see in the pictures that its not building up much heat with this method
