Well with the wheels away being rebuild I've turned my attention to the side covers, the original ones are in pretty good shape, the LH one had a small crack, just to cover all bets I bought a pattern LH cover and a pair from eBay.
The original LH cover was strengthened with fibre glass on the inside and the crack filled with superglue then sanded, you can still see a small line but it's OK for me.
The pair that I bought on eBay were a bigger challenge, they had about six coats of paint on them, I sanded one down for two days then resorted to the DOT 4, that shifted it.
All the panels were then sanded smooth, any small imperfections were filled with superglue and sanded (the same way I fill panels on my models using an accelerator), given a grey undercoat (UK Halfords plastic primer). Then 2 coats of Ford Graphite Grey, and they have just had a coat of clear, they still have an orange peel effect but I'm pleased with them.
Cheers
