Galvanize Tanks

[cool_hardware52]

My Galvalite Project...
Twin 38s from Surplus WWII Oxygen Tanks
- I followed Captain's advice and refinished these with Galvalite over a year ago. They now have worn a patina in the rub points of the paint surface that looks like Sea Hunt Mike Nelsons tanks. No scratching or chipping so far but, I lay them on either wood or carpet... Not concrete. These DO have really old galvanize under the Galvalite. I blasted them with a fine mix of aluminum oxide and glass beads before painting. No primer as I understand the zinc paint creates a galvanic connection with the steel, so that the zinc corrodes instead of the steel.

Gotta love bushed down NGT O2 bottles. Nice finish. I will add that a perfect coating of zinc is nice, but not really necessary. The zinc is a sacrificial anode that protects the steel even if it is scratched of nicked up.

What kink of bands are you using and how are they connected to the back ( plate ) ?

Just paint it, use a foam roller, 3 coats, cure for 2 weeks.

I'm concerened about filling in the stamped marks.

As you allready know about Galvanised tanks they are allready know they are hard to read.

Three coats and I don't think I will be able to read any of them.

Did you paint one coat then dry, and paint another coat then dry, ect. ect.

- The bands are original US Divers that were vinyl coated. They were in pretty bad shape with rust under the vinyl. I soaked them in acetone to get the vinyl off. Then, I gave them the same sand blast prep as the tanks and painted them with the Galvalite. The harness shown is original. I have since then, made a new harness. This direct harness (rather than a back plate) is very comfortable and positions a double hose regulator perfectly against the back.
- Yes, the paint does fill in the lettering. I think if I had masked it off before rolling on the paint, I could have covered the lettering with a thin coat of silver. Or, just used a small brush to paint that area with Galvalite and make sure it doesn't pool in the letters.

That's cool, you have a US Diver's / Voit double tanks.
