This is a question I asked myself this weekend. I sikaflexed in my windscreen and was looking at the fiberglass fairing and trying to figure out if I needed to go over and around the sika or could go right up onto it.
When I first started the sikaflex for the canopy, I had a spare piece of powder coated material to which I did a standard sikaflex attachment both of plexi and fiberglass. It is well documented that Sika bonds really well with both. The question in my mind was, can you put wet fiberglass onto a sika surface and expect it to bond properly.
I mixed up standard epoxy resin and squeeged it into 8 oz cloth. I applied this a couple of ways to cured sikaflex that was bonded to my original test surface. Let it set up over night and then tried to pry it off. No dice. The sika rips before it lets go of the fiberglass.
Thus the question is answered. Fiberglass can be applied to Sikaflex and it will bond very tightly. Thought I would share this experiment with the group.
