So luckily this is not for l'il (my 08), I noticed the other day when cleaning off the road grime from our 2days of winter this year ( :lol: ) that the drip channels on the roof of my 00 Expedition have lost the paint at the corners and some rust is forming. Short of sanding, priming & painting, any other easy/cheap fixes patches? Luckily it's not the entire length, just a 2' or so long section, but obviously want to fix it now before it rusts thru & we get an internal shower anytime it rains! :shock:

TIA

It is rusted through?

If not then you can get a rust converter that takes a rusted area and basically coverts it into a sealed protective coating. You can find at auto parts stores. It will protect the area stop the rust and even be painted over.

+2 on what surfscape said, you can get a rust inhibitor and it will let you paint over the area and stop rust. I got mine in a spray can, it's pretty common now I think, as long as it's only surface rust.

Thanks, so we're not talking spay can primer right, it's something that actualy stops rust, like a rustolium in a spay can?
I'll need to go by an auto parts store and look on the shelves.
Do I try to sand the rust off before using one of these items?

Thanks!

Preparation of surface instructions are probably on the can itself. I'd follow those, as it's their product and they would know how to best prepare the surface for painting/coating.

They have spray and brush on. In the gutter area you might use the brush type as it puts a nice thick and controlled coat. You will need to wire brush or 3M pad the loose rust of but not clean it to shiny metal as the converter uses the iron oxides to bond the coating. When it's dry it will be a hard coating over the applied area. It really works well and done right is pretty permanent.

Thanks, I bought something in a spray can, said to apply 2-3 coats w/i 2 min of each other, allow 24hrs to dry before topcaoting with paint. Said it would turn black, as of an hour later it was still clear I'll check it in a bit to see if it cured black, other wise I might need to return it to the store and ask why?

I wire brushed the areas first. It was actually easy, the spray came out very controlled, much easier now I have a garage and rolling steps
