What glue to use for deck lid seal

[lada03]

Hi Guys,
My rubber dexk lid seal became loose on my 81 targa. Can someone please recommend what glue to use to secure it back on?

[Bill Douglas]

Mine doesn't have glue. It just sits there on the lip below the decals.

3M Super Weatherstrip Adhesive

This doesn’t get glue

Not sure if its origina, but looks glued to me

No glue!

Look at the edge of the seal. It has a slot. Clean all the crud off the paint, hose down the seal and the lip on the body with WD40. It just slides on from one side, easy to do.

Some obviously someone overdid the glue down. Should fit onto the tabs and the way it’s configured snaps into a lip secure and snug when new, but as they become old and brittle the rubber starts to chip and break off causing to loose that grip. Maybe the prev owner didn’t know how to attach it and glued it. Your pic isn’t clear, but looks a bit in bad shape. If it’s still flexible, I’d first remove all that old adhesive (elbow grease and plenty of wd40) off the bodywork, and if the old seal is salvageable then clean off the old dried adhesive completely. So ONLY IF it cannot be pressed back into its channel should you reattach with 3M glue in the channel only at the surface of the tabs, which takes a bit of finesse, working a small section at a time. Can’t just lay it down and snap it in. Keep in mind the 3M if you choose to use it on clean surfaces, works like contact cement, both surfaces need a light coat, not a glob. Or get a brand new seal and pop it on with No glue. Mine is on its way out, 45 yr life expectancy…I’m trying for 50.

Thanks for the great suggestions. I will clean the paint and seal itself with wd40 and see if
It will hold better. When i secure the seal along the edge the other side of it is not flush with the body. It is higher and there is a gap

Never had glue when your car left the factory. It may been added at some point instead of a seal replacement....

Cheers

Water accumulates under that seal when I wash my car so I pull mine off to dry the area. Takes a few attempts to get it back on properly but yea, no glue

Steal your face right off your head. He’s gone.

I agree ramonefreak, I recall on another site someone had a rust prob with the front trunk seal accumulating dirt and water too. Coming in from a rain or washing and leaving both lids shut for weeks/months lead to rust under gaskets and body channels. Not sure if this was a long hood or impact bumper mid-year. I run a air compressor top to bottom to clear out any leftover water after washing and always avoid rain when possible. Can’t let any water be allowed to sit and maybe try to air-dry evaporate on its own depending where and how it’s stored.

So the old glue comes off but not easily. I picked away at it with my finger nail, flakes come off but some of it is really on there

Do you guys recommend soaking that area in wd40 and then using a rag to whipe and chip away at the old glue?

Would a dish washer brush work? I obviously dont want to damage the paint, but it may need some hard scrubbing to remove that crud

This stuff works great - in a ventilated space

If you have a decent size chip of that old glue, not knowing exactly what it is…I’d try soaking a sample of it in WD40 and another chip in mineral spirits. These two solvents will leave a sticky residue (not harmful) on your lid so clean it denatured alcohol as you go along with a clean rag each pass otherwise you just smear that sticky gum all over. Denatured alcohol will also remove thin layers of adhesive and not harm paint. BUT TEST zany solvent in a inconspicuous section to be absolutely sure !
Whichever works best, then carefully use a plastic putty knife to remove as much of the bulk of the adhesive as it gets soft, laying a solvent soaked rag over the area and top it with some plastic if really stubborn and hardened, should soften in a a hour. Dish scrubber will work but will clog up the bristles. Get the glue soft, rub and wipe it off. Just wipe often with a clean section of rag…that area should take about two, three old t-shirts cut into 5” squares!

Perfect! Thanks


I purchased the seal from ebay. Apparently this guy’s seal is a bit wider than our hosts. Should work nicely

For a scraper in a situation like that, I go to my favorite set of tools in my toolbox:

A hard nylon propeller from a radio controlled model airplane.

If you've got a local R/C model club nearby, pay them a visit. Broken ones are generally free for the taking. Otherwise a few bucks at the local hobby shop. You'll find unlimited uses for it where you want to deal with something without scratching things, such as lifting the top of the door trim piece to take it off.

Plastic Trim Sticks are commonly used in the industry. They're usually less than $1 each in bulk.

It should not have been glued at the bottom like that. Either no glue or just a dab at the corners of the grooved part to keep the edges down. Prepsol or 3M adhesive remover will remove the old glue.

I ordered the plastic scraper from
Amazon
Hopefully it will help

One of my favorite non marring glue scrapers is a bamboo chopstick with a wedge carved on the end, when it gets dull just sharpen it again. It gets into tight spots.
