Default Prymol alternative

Hello all. I've re-posted here as was in the wrong section initially
I am looking for an alternative to Prymol (no longer available anywhere) to apply to solarfilm to enable me to paint onto the film and the paint to adhere firmly.
I have read that roughening the film can give a reasonable surface and have found through experimentation that this works on solid/sheeted surfaces. However, several of my covering projects have open framed areas or stringers on formers (the Hurricane being and example). I find when trying to roughen unsupported areas that I'm just pressing the solarfilm which "gives" and subsequently only the film that is attached to the stingers is etched and the unsupported film isn't.
That is why I'm looking for an alternative to Prymol that I can apply with either a cloth or brush that will provide a good key for paint.
I am UK based so will probably need UK based suppliers of the alternative.
Thanks for reading.

Hello bud
have you tried using a fine grade steel wool rather than " wet n dry " I believe Tony Nijhuis did an article recently on painting - film finishes, in a recent rcm&e. And no i don't buy the mag either.
Do a search on the web page. Model flying .co.uk.

No...never did find an alternative. In the end used a very light sanding with wet and dry paper. Seems to be working OK
