Hi Nigel, Welcome to Scimitar ownership
That's an interesting car, the paint is obviously very tatty, and it's stood a long time, but there's also evidence in the underbonnet photos in particular that at one time it had a lot of care and attention.
As for the paint and body, I think the key thing is to get it as dry as possible before repainting it. It'll need all the existing paint rubbing down dry, and preferably the body kept in a warm place for a while before re-painting. If you do a search on here for "osmosis" and "microblistering" you should find loads of useful info.
If you're in Crowborough then you may be interested in the Sussex noggin & natter
. Included amongst our members are Geoff who's a current Coupe owner (not the one above though), and Tony who used to own one. We'd be pleased to see you there!
