lol.
The best thing I've found is to use Araldite (the two pack mix stuff), and some strips of old net curtain.
You build it up behind (as you would if you were fiberglassing something), out of sight.
It'll be stronger than before and waterproof, so won't fall apart over the winter.
I tried this on the mounting point of the tailfin of my 400 Impulse last year, and it's still going strong.
(Oh, and I used it after the plastic weld stuff came away from the bodywork... soooo much better.)
