Best adhesive for v-cuts in foam?
I have made a pattern of v-cuts in 1/4in. closed cell foam, and intend vinyl to lay upon it. I have tried two times so far using "Performance Hi-temp adhesive" and 3M general trim adhesive. In both cases, I would slowly roll the vinyl outwards, from a center line, depressing the vinyl into the v-cuts as I went. Unfortunately, the vinyl really didn't want to stick into the cuts too deeply, and would eventually pull away.
I am of the opinion that the adhesive needs to be stronger and act more like contact cement that sticks instantly, but would like to hear what some more experienced trim folks have to say. If it is a glue issue, what would you recommend? I would prefer aerosol can, but if not possible due to my needs, I could buy the HF sprayer (How would you clean that nozzle, btw?!).
