drip rail filler

[dubie]

Is it 3M that makes the drip rail filler in the caulking tube? I took all the old silicone crap that the PO installed and am looking to fill it in .

Tim, talk to an experienced body man at a good body shop, they can tell you what you need. That area is too important to take chances on with second rate material.

This has been a topic of interest to me for the last year or so. I redid the rain gutter on my 69 about 2.5 yrs ago. I used 3M's Fast & Firm to fill the gutter. First I cleaned out the old, prep'ed and POR-15 the gutter. I used POR-15's apoxy puddy to fill the seams, then used the Fast & Firm to fill the gutter.

I put it on too thick the first time and wasn't happy with teh results. So I cleaned it out and redid it. Thinner this time and a lot nicer job. I waited a few weeks and primed & painted the whole cab top. Now the truck has set inside my basement garage for the last 3 or 4 years. I have small cracks forming in the fast & firm that I have to figure out how to fill with touch up paint. They are only about 1/8" long but they are a problem.

Now my other truck had some rust problems onthe drip rail, So far I have cleaned & POR-15'ed, then apoxy puddied the rail forming a couple inches of the gutter side with puddy at both frt corners of the cab. I'm thinking I should go ahead and use the puddy to fill the whole gutter.

So at this point I believe you should try to find some apoxy puddy to fill your drip rail. That's my $0.02 I would like to hear what others have done & long term results if you have any.

I prefer 3M 8115 panel bond adhesive since it dries hard as a rock and won't shrink. It is a self-dispensing two part material that holds primer and paint great. It's a little expensive but it is a forever solution. The only downside is you need the 3M gun to dispense it.

I hope this isn't a stupid question but why doesn't anyone use lead as a seam sealer?
It seems like everyone's seam sealer cracks eventually and needs replacement. The only reason I can think of not to use lead is that it's toxic to the body. However, there are safe methods for handling it.
Does anyone have an opinion on this?

If you use the 3m stuff make sure to wear rubber gloves, it is next to impossible to get off. Acklands should have it.
