> Hi Netters, > Some one recently asked about painting WAFs. If you go and talk to your local auto body repair shop you can ask them how they prepare metal for painting. My local painter said that he now used " Green Epoxy Primer". He thinks that it is the best thing that has happened in years. I bought a can (very expensive), it works like a charm. Be sure that the metal is free of oil &/ grease.Use a small syringe to measure out 5 or 10 ml of epoxy and in my case an equal volume of hardener. It is very fluid, It contains a solvent that rapidly evaporates, the epoxy cures in about an hour. If there is any left in the mixture give the metal a second coat. > Regards > Harold Woods > Orillia, ON. Canada. > Netters/Harold, The US Navy uses "Green Epoxy Primer" on the metal structure of Naval aircraft that go thru Depot level rework and it proved far superior to zinc chromate primer. It is used to protect steel parts as well aluminum such as 7178-T6 and 7075-T6 which are always trying to change back to a white powder from corrosion. The Navy used to spend a lot of time cleaning and stripping off zinc chromate to inspect structure and then repainting with zinc chromate. When the change was made to the epoxy paint it became a wash the structure, blow it dry, and inspect for loose or missing paint ( which indicated possible corrosion). The missing paint area was inspected and any corrosion was treated based on type of structure metal and recoated with "green Epoxy primer". No top coat was applied to the interior structure, just the primer. "Green Epoxy Primer" is not used for joining bolted parts together. That is where zinc chromate was still being used. With the EPA trying to get rid of chromium from the environment I am not aware of what is being used at this time.
Harold is there any identifying name or product information on your "Green Epoxy Primer"? It would make a good starting point for finding it this side of the border. Bob Morrissey New Bern NC
