Which Adhesive for Tank Knee Pads ?

Nowadays I would try clear silicone glue. Comes in tubes from craft shops. It keeps things in place but can be peeled off if need be. Unlike Evostick which is filthy stuff.

You must roughen up the inside face of the knee pads which ever type of adhesive you use. I used Evostick satisfactorily.

I use double sided golf tape on my slimlines. Model 50's still well stuck since 2000. No luck at all with others, using silicone and even super glue.
