I'm really keen to try the PlastiDip range. Tough rubberised-plastic spray on coat that you can roll/peel off and change the colour when you want a change. All colours come out matt - but there is a 'glossifier' + other surface treatments. I've taken all the stickers off my panels, so no issue there (just custom 'XT660X' on the exhaust shroud). I've been imagining my bike in matt red (or orange) - maybe with a gloss white off-centre stripe, and then I found this stuff.
I imagine that the same flame prep technique applies to get rid of the release agent - a bit of experimenting? Actually I would (will?) try with just a thorough de-wax first - the finish is not meant to be permanent anyway.
