I am midway through building my tweeter pods that are mounted to the internal mirror cap. I have screwed the mounts that came with the speaker to it, I then used P38 [?] poly-filler to build it up slightly and then went over with a first layer of P40 filler. The issue I am having is that neither of the products are really bonding very well with mirror cap. Can anybody suggest anything that I could use to help keep it bonded together?
