Looking for advice on re-blacking window trim
Hi All! I'm currently doing up a nice 1990 Swift Corniche 14/2 - and ive got to the point where i'm looking to spruce up the outside appearance. All the decal vinyls have faded to white, and the trim around the windows which covers the seals has faded to
a nasty powdery grey - and due to being much loved by previous owners in some places has started to rub off. I was wondering if anyone had any idea what the best method to use to re-black (or re-grey which ever the colour used to be) the window trim, and if
anyone happens to remember what the colour of the decals were on a new 1990 Swift Corniche. From doing some hunting for photos, most now have faded to white, the ones that survive are dark grey - but is this faded black?

Some ideas, tips or ways people may have resolved this in the past would be much appreciated
