I have been sanding the paint off of an old 1436 Alweld I recently bought. What a job it has been! I will never completely strip another boat as long as I live. To prep for the painting I rinsed the boat, then used 80 grit sand paper to scuff the surface of the entire boat. After that I thoroughly washed the boat with hot soapy water and a soft bristle brush. I then applied a mix of vinegar and water.
After the boat dried, I applied a light dusting of the primer. I then finished with a second coat that completely covers the aluminum but just barely. Well, it's been about 3 and a half hours and I can still scratch the primer off with my finer nail.
The directions on the can say the surface can be sanded after 3-4 hours, but this stuff would come right off it I touched it with sand paper. Any tips would be very appreciated. Does it just need to cure longer? A lot of people seem to swear by this stuff but I'm not having much luck. Anyway, thanks in advance.
