rusty door prevention

[bigblockfrank]

ok got my doors sand blasted, new outer, inner skin. my question what are you spraying down in the door keep it from rusting. course this is after painting the door. i heard gun oil,silver dollar, wd40, ect....? im thinking gun oil, it has teflon in it. also i bought new outer sweeps, and installed them.

Any good painter would paint the inside of the door especially if it was a hot rod or custom,and new door sweeps.

well..... will the paint seep down in the seams (to mimic water travel). its hard to get a paint sprayer down inside the door at the very bottum. all i have in there now in some weld thru pimer, and what paint i could cover. will that be enough?

WD, etc will eventually dry out.

What you want is cavity wax. It's sprayable, and as implied, is a waxy type penetrant. Use it all the time at work when repairing/replacing a door. It is in most newer cars from the assembly plant.

This is what I use, there are others by other suppliers.

Have also used this, but our owner signed a deal with our paint jobber for 3M and now we can't buy Kent 🙁

I prefer Kent products over 3M in most cases, but I have to play the hand dealt, I guess

Love to hear how you're going to accomplish that

Any "good" painter would epoxy prime the inner shell and the inside of the skin, if it wasn't e-coated, prior to assembly, then follow up with appropriate treatment after assembly. If the skin is bonded, there really are no issues with coverage on the hem, as the bonding agent contains some corrosion protection, and the cavity wax will seal out any moisture. I just spray along all the edges, and the lower 8" or so of the outer panel, and keep spraying until it runs out the drain holes.

exactly thats like the hioney coat stuff we used at the body shops , it was a waxy spray that we used in rocker panels and places that could trap and hold water after a repair, this goes had in hand with a good seam sealer as well
