Those of you using ABS (plastic) cowls

Be forewarned that Epoxy doesn't stick to ABS for very long even if you rough up the plastic. About the first time you run the engine, it comes loose.

The solution is a can of ABS pipe cement from the discount store. Use the swab in the can to attach your fiberglass or CA hinge material. It will not get really hard for a few days. But it never comes loose.

You can then use epoxy on whatever you attached to the plastic.
