Adhesive Help

[BigBoy99]

I put vinyl door edge guards on my wife's car. The U-shaped vinyl strips had double sided tape on the inside to stick the guard to the door edge. Worked just great but now, 6 months after the initial installation, the double sided tape is losing it holding power and the door edge guards are coming off. Probably due to the outdoor weather conditions.

I would like to find some adhesive which I can use to permanently "glue" the edge guard to the door. I've tried construction adhesive put it won't stick to the door's coating. Any suggestion on adhesives which will stick vinyl to the cars outside finish? Thanks.

Surface prep correctly, and try some 3M 5200.

It will NEVER come off (without damaging what it's
attached to).

I had the same problem and went another way. I used black rubber hose, in the right diameter, and cut it down the center to make it U-shaped. I cut it to the length I needed and slipped it on the door edge. It worked for me and lasted a long time. I tried other types of hose but rubber was the only stayed on. It's also enexpensive

5200. Make sure you never want to take it off however

Unfortunately, vinyl (polyvinylchloride/PVC) material is similar to polyethylene and there is no adhesive that will be guaranteed to work. Both materials have a surface impervious to anything, so only a surface contact is possible. Both materials also give off a volatile organic compounds (VOC) over time that is much like oil, so it actually sheds adhesion. Plastics also have a very large coefficient of expansion/contraction and in winter conditions a strip 8' long can contract 1/4" from summertime temperatures. If you are talking about a bottom seal strip on the door, ice can form and freeze the strip to the concrete floor and it will pull off the stripping when opened. Believe me, I have had it all happen to me living in the far north country.

I am thinking you are talking about a door seal strip that is applied to the bottom of the door?? If so, I have successfully installed them using roofing nails and they stay forever, but I have wood doors. If it is on the door frame around the opening, try to find a way to mechanically fasten the strips to the frame. Sometimes a wood trim strip or metal strap nailed or screwed to attach through the weather stripping into the door frame will so the trick.

Try Gorilla Glue Bonding Agent. In the silver tube at Walmart. It bonds everything and is clear and water proof. I have used it on car trim, boot soles, furniture repairs, etc.

Good stuff.

You say it's the car your wife drives, I'd go with the glue (5200) suggested above. Now, if it's YOUR car or truck, I would think that's good enough reason to go vehicle shopping! They make it so easy; just sign zee papers! Is this that strip that runs vertically down the door edge to basically protect the car parked next to you and your car's door edge? Yeah, that glue should work. That strip is almost a necessity in today's parking lot world.

The 3M double sided tape that's made for attaching trim to cars should work. It's all that holds the black rubber side mouldings on my Mustang and it was applied 15 years ago.

The 3M double sided tape will work.

I’d say but replacements but get 3m adhesion promoter. It’s what body shops use

The other option is go to the autoparts store and buy a different set of door guards, that have butyl adhesive in the center. I've had them on my cars for at least 7 years - they've lasted through hot summers and cold winters. The only prep I did was to wipe the edges with lacquer thinner.

Thanks for the help. I'll check out the 3m 5200. That sounds like just what I need. I figured you guys know just about everything!
