What would you suggest to use to glue the rubber pads on the tank of a Triumph Bonneville?
The kind of the rubber pads is the thin ones used on the 1966/1967 models
Thanks for helping!

3m yellow or black weatherstrip adhesive in a tube from any parts house, don't coat the entire surface, just a couple circles or perimeter and an x. It's contact cement, put it on the rubber then squish it on the tank and pull back off to dry. Then carefully press it back in place. Do the outer perimeter well so you won't have loose edges.

Elmer's Rubber Cement
Apply to both surfaces and press together. Read the label!!!!. Removeable, with some effort, without destroying the paint. Never liked them on the 72 but they have been on my 68 for 15? years now.
The excess rubs off with your thumb. Try that with contact cement.

GE kitchen and bath clear silicone. A thin bead around the perimeter and smooth it with you finger.
I'm a plumber so I always have an open tube of it in my truck.

I glued pads onto my BMW tank last year, using 3M Super Weatherstrip Adhesive in black. First though, I watched a couple YouTube videos and found that less is more with this stuff. It is also necessary to remove the mold release agent from the backside of the rubber knee pads.

I laid the pads upside down on the bench and sanded with a random orbital sander till it looked like the rubber was a uniform, flat black, lightly scuffed surface. Then I scrubbed with a brush and some tire cleaner and hot water. I dried it with a hair dryer, but once dry, I could see there was still some whitish mold release agent present in some spots. I repeated the process and this time it looked uniformly ready.

One side at a time, I applied a light bead of adhesive, smeared flat, thin, and clear out to the edges with a flexible plastic putty knife, on both the tank and all over the backside of the pad. I let them set up till I could feel it was only a little tacky (wearing latex gloves because this is deadly stuff). Then I made sure the pad was positioned and stuck it on.

There is no adjustment, so be sure it is right.

Instantly, the pad was adhered and I could tug at the edges all around without any hint of it coming loose. You could use a paper slip sheet with this adhesive, to get the pad into position, but I took my chances without that. My tank has well-defined recessed areas for the pads, so they were easy to align. On a Bonneville tank, I would want to mark the outlines somehow before applying the pads, maybe using a dry-erase marker, or outlining the pad area with painter's tape.

One year later, they are still in place. 2c

3M aerosol trim adhesive ....about 20.00 US a can sold at Auto Paint Supply stores by far the best product.

That's a good choice too. 80 is regular strength, 90 is high strength like for vinyl roofs but thicker consistency. Either should work very well.

I used this on my 66 Bonneville rubber tank pads 10 years ago, bike is ridden regularly in all weathers and no problems what so ever.

It's a very thin double sided tape, I believe used by car manufacturers for attaching body trim.
