Question about drip rail material
 

Im thinking about repainting the white part of my cab and I was wondering if that material that lines the drip rail is necessary anymore (it looks to be a little dried up anyway). I plan to chisel and a wire brush to remove it.

Re: Question about drip rail material
 

Its Absolutely nessasary. that seam is more complex than it looks, and the old sealer is keeping water out of the inside of the roof, and out of your cab.
If its in bad shape, yes it is a good idea to cut it all out, just as you descibe, but you also need to put some back in its place.

Wire brush all the old out, lay down some epoxy primer and flow on the 3m 8307 - do not use anything else! - sand if needed, prime if you like, and spray on your white. That is the only way to do it right...:metal:

Love that 3m product! There's comparable sandable flowable seam sealers as well but definately good advice, I used a product aloes plyo grip made by valvoline and it worked great but 3m is hard to beat

I see that 3M 8307 comes in 200ml cartridges. How many cartridges does it take to seal the drip rails?

If you are just looking to barely put a bead down in the seam you can probably get away with ony needing one. If you really want to make the drip rail cherry and build it up all the way around and smooth it all out you will need two.

Anyone have any pics of this process? I am going to have to do this as well.

thanks

Cataliyzed seam sealer is not the "only way to do it right". In fact, in a recent thread on this forum it was stated that that type of seam sealer does not stand the test of time.

Use a quality urethane that you can push out of a caulk gun and it will be easier to use and will last the life of the new paint.

I don't have any pics online but have some at home I could upload. One tube did my entire drip rail perfectly. My friend just did his and one tube was enough for him as well. We both bought two and ended up taking one back. If you use two tubes I would expect the drip rail to be nearly full and not be much a channel anymore for water to follow...be sure to rent/borrow the 3m gun that is made for these as well - it was different than other epoxy guns I had used which didn't work with the tubes...
