So.... POR 15 metal ready sucks at preventing flash rust. Even in a garage that is ok at sealing.
Spraying a two part epoxy primer is out, and my pans are going to be bare metal for a while since I have to remove the cross brace in the pan and the center tunnel to attack the rust in there. Is epoxy primer available in cans? I need to prevent the metal from flashing and rusting agian while this is done so I can do it all with por 15 excepting the area where the brace/center tunnel mates with the pan, which of course will be weld through primer. Also any reccomendations on a good weld through primer? U-pol I hear is the best and worth every penny vs 3m or the others? Thoughts? |

I used the cold galvanizing compound where I was going to weld later with good results. Just don't make it too thick, and wear a mask when welding it because the zinc smoke is not good for you. I don't think you can paint over the galvanizing compound though. I used eastwood self etching primer in rattle cans for protecting metal while in process. It is not completely waterproof and will let rust form after a few months if it is damp. Someone makes two part primer in spray cans, where you push a button to mix the parts. I think eastwood sells it, never tried it myself. Now I mix up an ounce or two of two part epoxy primer and brush it on for touching up small areas. Saves the trouble of getting out and cleaning the spray gun. John |
