Technical help with rust in door seam

My Brookville roadster somehow got water inside a door. The seam at the bottom where the outer skin is folded over is rusted. What could I do to neutralize the rust it before I paint?

POR-15. Check out Eastwood.

 

I'm a big fan of POR-15. It neutralizes the rust and you can paint over it.

 

Thanks for the reply's. Would POR 15 be thin enough to seep in between the door skins? Or could I thin it?

You could also use a product called rust mort, works for me.

 

Yep, just poor the POR 15 in the seam, no need to thin. When it cures that will be the strongest part of the door.

 

Eastwood is also an alliance vendor, so you can't go wrong!

 

Before you use the Por 15 paint itself you must use their marine clean degreaser and than a metal prep solution. If the rust has started to grow than maybe open the seam a bit.

 

Ospho!! Then clean and paint!!

 

Doesn't neutralize rust, it encapsulates rust & as long as there is no break in the coating the rust will stay there doing nothing forever.

Thinner than water.

It's should creep thru the seam, probably run out into the floor too. Lol.

 

Metal Ready to neutralise the rust, then paint with POR-15

Agreed....Metal Ready and then POR. I've had nothing but good success that way.....

 

Off topic vehicle, I had rust in the door seams of a chevy traiblazer, the seams are probably tighter on this than older cars. Wire wheeled the inner door bottom seam, used POR15 on the inner door bottom and inside the door shell about 8 inches up the door, topcoated the visible areas with duplicolor factory match paint. 2 years later daily driving in chicago snow and salt, no rust bleed thru. The POR15 ran out of the door drains and self leveled in the bottom of the door, I don't think it climbed the seam, so application on the seam itself to run down is needed. Made a hell of a mess, lay down cardboard and have POR15 thinner available to wipe down the drips from the door drains. Plan on checking it frequently as it drains / drys.

 

SEM Rust Seal is worth considering. Pour in and let drain.

 

Thanks all for the information. I have ordered some POR-15. After I clean it I may use Metal Ready to etch it.

The marine clean and metal prep will be plenty of over kill... por15 will do the trick and your car won't see salty winter roads like they did in the past!
