Hi Bob, vinyl stripes/decals won't hide cracks in fibreglass I'm afraid as you get bubbles coming through from underneath.

I had that happen where I'd cobbled together several bits of bonnet into a scoop on my Spyder, the flaws were practically invisible to the naked eye but allowed hot air to permeate through from the engine bay and raise little bubbles in the roundel on the bonnet.

As for the cracking issue, the problem could be down to the use of modern paint rather than old-fashioned cellulose. Hopefully I haven't got the wrong end of the stirring stick, but the way I understand it is that modern two pack sets rock hard while cellulose remains flexible.

My Spyder bonnet has to be flexed quite a bit at the sides to open and close it, which I've been doing for the last four years, and I've had no cracking anywhere (apart from the scoop as described above and which isn't down to flexing). Perhaps modern paint is just too 'good' for a fibreglass car? Just a thought.
