Seam Sealer?

What would be the best Seam Sealer to use on Door Jambs for example where metal meets metal? I'm looking for something exact or close to factory.

Thanks

Re: Seam Sealer?

I got some of this stuff and believe it would have been similar to factory. It is white caulk. But I've seen lots of posts here on the forum about people getting self-leveling epoxy type seam sealer, which makes a better looking and more permanent seam (not factory but you did ask about the best).

Re: Seam Sealer?

Looks good. For my Driprails I used 3M Self Leveling Sealer, a product you need to apply with a 2-cylinder caulking gun, and the stuff worked great. But for seams more visible like the door jambs, I'm looking for more like the above. Especially using it on vertical surfaces. Although with the Driprails, as we know, some of those are also vertical. The trick to that was to use less material and apply it at a slower rate. Appreciate the recommendation.

I have had really good results with the 3M in the jams.

3M Heavy-Bodied Seam Sealer, 08308, Two-Part, Self-Mixing, Automotive Epoxy, 200 ml/6.75 fl oz Cartridge , White

Good luck

Re: Seam Sealer?

I've used this SEM sealer a few times over the years. It works well.

Each tube comes with a screw-on nozzle, but they are really only good for a single use. But I found a package of them on Amazon for very little money.

Me too. Their Trim Black rattle can paint can't be beat. When you first spray it on, it looks like it will have an orange peel finish, but it flows out and becomes a smooth satin finish. Also dries enough to handle in 10-15 minutes, unlike other brands which stay tacky for hours, if not a day or more.
