Drip Rail Sealant ?

[54blackhornet]

Has anyone used self leveling rubber roof sealant on the drip rail channel ? According to the mfg it should work but thought I would ask you guy's before attempting it. Thanks

I would use seam sealer, I believe that's is about all anyone uses, and what the factory used. When it comes to seam sealer there are alot of options, some better than others.

The previous owner used some kind of sealer to fill in the channel above the windshield on my '70 - then painted over it with the two part catalyzed urethane - this was about 3 or four years ago - he must not have chosen the right stuff because it has cracks beginning to open up and not just in the paint.

Sorry I can't tell you what he used or why it cracked so I'm not much help there but I can suggest that whatever you use is going to stand up to the heat/cold cycling and ultraviolet and or infrared radiation from sunlight; and maybe has a similar coefficient of expansion as both your sheet metal steel and whatever paint you end up using.

I wonder if auto body lead solder might be better in that location?

Probably 3M has something easier in an elastomer.

3M makes a seam sealer that is sandable and paintable.

3M Seam Sealer, at any auto paint supply company. That's what I used.

I can tell you what not to use - dynatron 550 seam sealer. Not self leveling, not user friendly, not easily sandable as it says.

I have to grind it all out and switch to something self leveling

I'll second that!
