I painted my shop basement galvanized window well with oil based paint. It has all peeled off.
I can scrape it off but how do you paint this product and make it stick?
TIA,
Don

There are many others if you google painting galvanized steel or whatever the metal is. I had fair luck using a automotive primer in a spray can. BUT.. I have forgotten what I cleaned the metal with before putting on the primer. Probably some automotive primer pre-treatment. Sorry I forgot what I used.
A heating/ac installer told me years ago to wipe galvanized metal with vinegar before painting. Supposedly has a chemical affect that lets paint adhere. Been a long time but I think it worked.

Wash the galvanised metal with TSP,rinse, then use a latex galvanised metal primer such as Suprime 3 by Pratt and Lambert.Use it all the time and it has lasted without topcoat for ten years on downspouts.However it is intended to be topcoated
