drip rail sealer

Hey guys
I am in the process of starting to refinish a new cab project of mine. The sealer that is in the drip rail is all dried, cracked, and falling out. I had orignially considered shaving it but am not sure. What kind of sealer do you use if i decide to keep it?
Thanks

Shave'em Off, Cab Lines Will Look So Much Smoother. Thats Just My 2 Cents.

Thanks

Re: drip rail sealer

I think shaving is hard, and if you drive in the rain at all or your truck sits outside, you'll live to regret it.

I agree. I owned my 72 Malibu for 5 or 6 years before I bought my 71 convertible. The hard top 72 has drip rails. I never thought about what drip rails do. Then one day I was in the convert with the top up because I was caught in a rain storm. The rain quits so I roll down the windows. The first corner I went around dumped all the water on the roof into the open window.

Re: drip rail sealer

How much of the 3M automix #8307 would be needed to do our trucks? I see that they are sold in 200ml packs...Is one 200ml kit all that is needed, or does it need more than one?

Mike

Re: drip rail sealer

3m body caulk -- water based. Clean out rail completely down to the bare metal. Read the instructions if you should prime before applying or not. If rust is found use a converter first. It can be smoothed if needed with a wet finger.

Re: drip rail sealer

Body caulk will tend to crack over time. I used the 3M 8307 seam sealer and it is as close to factory as you can get...only better. Just make sure you clean out the old stuff/rust & paint.

Re: drip rail sealer

Agree with Botietruck, I used seam sealer in a caulking tube --it was water based.

Re: drip rail sealer

I used Fast & Firm, but didn't like it. It was easy to use, but took about a month(no kidding) to completely dry, and now is starting to crack.
