Replacement T-Molding not staying in slot - suggestions?

[cmoses]

I am replacing some T-Molding on my project MAME cabinet.  The original T-Molding was in pretty bad shape so I took it out and have since restored the cabinet.  Now that I am replacing it with new T-Molding it slides into the slot very easy without much resistance.  I am not sure if there is a something that I put in there with the T-Molding to make the fit tighter or if I will have to use some glue or adhesive of some type.

Can I get some recommendations as to the best way to keep the new T-Molding in place?  I was hopping to get some suggestions from people that have run into the same issue.

I'd use a glue gun.

I've used masking tape wrapped around the spine and it creates a very tight seal. In really bad t-molding slots I've had to refill them with bondo and recut them.

I had issues w/ the far ends staying in the slot where they were going around corners.  I used a little super glue and they haven't come out since.

I've used this method and it worked for me.

This is also a good idea.  Wouldn't have thought of it.  Thanks for putting another option out there.

Best to just shoot the glue in the slot and push in the T-Molding, then let it set?

As far as using masking tape, is one piece enough or do we need to do more?  The T-Molding goes in, a little resistance, holds ok on straight areas, just mostly at corners.

Yeah, load it in there but be quick about it as hot glue sets up fast, fast, fast.

I thought about using glue, and I was concerned about replacing the t-molding if it got nicked up or something. I'm sure it would work though.

That's what's so great about hot glue.  It holds it well enough, but if you need to you can pull the t-molding out, as well as all the glue, with little trouble.

I had this problem once

To remedy the situation I filled the groove with tacky glue, then pushed hard on the molding & then ran a really tight strip of blue painters tape from one side to the other.....every inch or two.

After it cured all was well.

Had not heard the term "tacky glue" so I Googled it.  Are you referring to Aleene's tacky glue product?  Or something else?  Aleene's is just a thicker glue, so it holds better initially.
