Gluing To EPDM
I have a EPDM rubber roof. I need to attach a galv. steel plate to the roof to the roof for a mag antenna. What is the best glue for that? I will be using self leveling Dicor around the edges, after...

I tried doing similar thing to what Kiwi wants. Covering the hole after I removed the TV antenna.
One problem with glue is that roof is not flat. Glue doesn't work well when there are gaps between two surfaces. Sealants fill the gaps, but I don't like that Dicor has a lot of flex, more than cheap urethane caulk.
Another problem is that EPDM rubber is very thin and I could see how it lifts off the plywood when something pulls at it. The plate - if glued properly - would stay on EPDM, and when enough force is applied, it will lift the piece of EPDM and rip it off.
Eventually decided to put 2 small tapping screws through the metal plate, with Dicor under it and around the edges.
