Advice on Gluing vinyl on Trim

[phil1800]

If it is ABS or PVC, this works fine. I use this glue for the piping of my Pool with very good (pressure proof) success. Please consider that the surface of the plastic part is attached by the solvent in the glue for better tack. I means that the surface of the ABS will be sort of 'milky' in appearance after the glue is applied, but is will be covered anyway. A bonding test is always recommended if you are not sure what your are glueing to what.

Update: So I took the trims out of the car to remove the sticky mess & trim them yet again with vinyl fabric.

Here is what the trims look like with the Vinyl removed:

The sprayed on contact adhesive has changed into a gooey mess... it was dry to the touch when stuck to the trim... why is this happening?

&... I thought the trims were ABS... but looking closely at them I believe they are GRP that used original ABS parts as the mold... you can see the texture of the original ABS parts on the rear side of the trims. .... The rear face of the trims is smooth, the viewed side of the part was rough, so they skimmed the parts with what appears to be bondo & then sanded them down smooth... the bondo is the green that you can see.

I have cleaned the trims off with acetone & paint thinners so now I will have to stick the vinyl to the GRP/bondo for a 4th time... As contact type cements are not working what about using GRP resin as the adhesive?

Update, I re-stuck the vinyl with contact adhesive & the trims looked fantastic:

For 5 weeks....

Then after high temps in NY everything came unstuck again:

It's very odd... wondering if there's a chemical in the vinyl that is reacting with the contact adhesive?

Your trim looks like my dashtop under the foam. My trim did not look like that it looked like the replacement I bought which is a thin black plastic. I think the light color dashtop and your trim are fiberglass (GRP). It is very hard to get fiberglass to stick to fiberglass but you can paint it. Perhaps you could paint the trim before gluing it. Not a good practice normally but you don't need much strength, just stability. I noticed that some of the suggested sites sold goods for professional use only. Be careful with that acetone and other vapors!
If I were you I would seek the advice of a boat-shop' one that does repairs. They might be able to do the covering for you using stuff you can't buy. It might save time and your health, and maybe sanity.

You really need to use something like this.

Thanks, that's a contact adhesive, no different from what I have been using.

Took the panels along to my local auto trimmer (Automat) to show the owner. Nothing wrong with the panels, vinyl or glue

I'm wondering if the GRP panels are absorbing the paint thinners & acetone that I am using to get rid of old glue & then after gluing when the temperature is elevated the remnants outgas & re-dissolve/react with the glue? The solution to this would be to bake the panels after cleaning (In the oven when the wife is out of the house of course )...

Use them to make a mold to cast new ones in a more tractable material, like paper mache.

I have used Devcon clear silicone adhesive on my headliner (+2) and other trim pieces. It has worked well although it must be clamped in place while it sets. It has worked well for me in the heat of the desert and it has not stained anything. Note it is an adhesive, not gasket maker. I bought mine at Ace hardware in the US. Gary

I was only half-joking. You don't need GRP to hold up the vinyl, which is all it's doing. At the same time you could mold in a flange so you wouldn't have to screw it into the plywood edge. Make extras and sell them.
