What a great result, looks better than most paintshops deliver.
Are you not a little worried to damage your beautyfull work, when you replace the doors?
I am thinking, when I will be painting mine, I will do it with the doors hinged (and opened)
But seeing your results I am getting more confident that good results can be reached.
I am now in the proces of sanding my Saab V4 1967 (also fiberglass) and so my Europa has to wait a little.
The lotus I bought is already stripped from its old paint, but someone sprayed primer thats already falling off.
Probably wrong paint or bad prep/ cleaning.
