I know you are across the pond somewhere, but, what type of primer and paint did you use? Can I use regular spray paint from wal- mart ( that's the store where all us rednecks shop, kinda like hardware/toy/clothing/hunting/fishing/diaper/pet/cigarette/grocery outlet mall, all in one!) I know it sounds too good to be true, but, I promise, they are everywhere! Anyway, painting over the covering is okay? Thanks for your expertise and you have a beautiful plane there!
Ordinary paint primer over Profilm ( Oracover) will soon peel off. I use 'Prymol' which is made by Solarfim and is an etch primer for plastic and metal surfaces. It can also be used for sealing the edge of covering.
It has the consistancy of water and you merely brush A THIN COAT onto the surface to be painted and it dries in a few minutes. It does give off strong fumes so use a well ventilated area.
Then apply a coat of model fuel proof paint. I use Flair paint. The first new paint coat will 'drag' a little and may require about 10% thinning. Don't worry if it doesn't cover everything with the first application. Allow to dry overnight and apply a second coat which should suffice.
The beauty of painting over a silver colour is that you can then scrape off areas of paint to reveal the silver underneath and produce a natural looking weathering effect!
