It might be somewhat weaker, but I didn't have 72 hours to wait for each one to cure and it's plenty strong to hold on the hatches. I just had some problems that weren't overcome yet.

1; The forward hooks were put on only about 10 hours prior to launch. 2: I only had 1 hook on each side. 3: The front straps were way too tight. My friend said that he didn't even dare open it because he thought he would break something. 4: I noticed that I did not have epoxy covering the entire bottom of the hooks. When I pressed them on, some epoxy squeezed out and when I let go there were gaps left that weren't bonded. The second time I filled in the gaps around the edges to get a good bond. 5: The sun was really cooking the non-cured epoxy. 6: The back ones were looser (about right) and they never came off.

Since I worked out all of these bugs (with Shawns help) I've had no problems at all.
