Hi guys
Its all over all the boards about using a product called Klear to tart up canopies, prep for Decals and also for a nice glossy finish but it is not available in the UK except by expensive import.
So with this in mind can i suggest this product

Quick Shine from a company called Holloway House, its avaiable from Lakeland stores for around £12 GB
OK its not cheap but i'm pretty sure its cheaper than the import.
I have tested it on canopies both by dipping and brush painting and it works fine.
I've also brush painted onto acrylic paints and it goes on just fine, brush on sparingly and it self levels a treat.
The Gannet below has had two coats and looks nicely shiny
