Rain gutter

I'm planning on using 3m 08307 self leveling seam sealer on my 72 rain gutter/drip rail and was wanting some input on how many cartridges it will take.

Not familiar with what you’re using but I used a full calk gun cartridge of roofing sealer to fill mine. Don’t know if that helps.

Re: Rain gutter

Was thinking of doing the same, don't know if its the same 3M number but the products that Napa had in stock it would take 2 most likely.

Re: Rain gutter

I only used one 200ml tube of SEM sealer on my Burban. So I believe one should be more than enough for a pickup.

Re: Rain gutter

I used maybe 3/4 a tube when I did mine. Also sealed up the floor to firewall seam with the same tube.

Re: Rain gutter

I used the same 3M sealant for my gutter. I was a little over zealous and filled it probably too much. I used just a bit more than one double tube. Knowing what I know now, I could have done it with less than 1 double tube.

Seeing where the seem is verse the bottom of the gutter looks like to me I'll have to fill it up at least 1/8 so it will stay above the seam and hide the spot weld marks in the valley.

I jacked the rear end of my truck up as high as I could get it to help even out the flow along the front of the rail. So maybe I should have just did it with the wheels on the ground. Might have been able to not use as much to get the effect you describe above.

I will tell you this though. It sets up quick after it stops flowing. So any tape, paper or plastic masking stuff needs to be removed within about 2-3 minutes. I had a thing area of tape that got set up under the sealer and I had to go back over it to seal over the tape. Luckily it will be painted over and no one but me (and now you guys) will ever know.
