Bob, that sounds like the way Ford would do it... not the guys in England. If they were layed up at Specialized Mouldings, I would think they would have used gelcoat. Back then, they did the best glass work there was. I have less trouble with the whole process using a gelcoat. But now with the high build primers using hardeners, the finshing of a non-gelcoated surface isn't all that hard to do.
