Preventing flash rust without spraying two part epoxy primer?, There has to be a way! Metal ready is not it! Options

[ghuff]

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.

I was thinking for some reason cold galvanizing compound would work well. The price is right also, 5.50$ a can at home depot and available almost anywhere.

I am going to try it. I am kind of agains the wd40 idea because I know from experience how bad any oil or petroleum stuff can fuck por-15 up. It will literally run away from a millimeter spot of grease when you attempt to brush it in, and it will do it slowly when it is almost finger dry too (IMG:style_emoticons/default/sad.gif)

When I am ready, I will just break out the 4.5" disc grinder with 60 grit wheel, vacuum the dust then etch with metal ready and por-15.

I am more looking for a solution with quick clean up.

I thought the pan was going to flash worse than it did, but it surprised me that it was as clean as it was when I checked it around 2pm-5pm during family move time.

Now time to remove the cross brace, center tunnel, and seat mounts.... argh!
