I am not am expert on clearing canopies (especially because I did not succeed) but I have tried, and I can paint a little. I am sure there are many valid techniques, and it may be that the actual canopy material makes a difference. I tried my best to apply Future to a BVM clear canopy. I dipped the canopy in Future, and had runs and sags and a few bubbles with Future. I tried airbrushing Future and got uneven coverage, I tried wiping Future and got streaks and a little lint from my clean rag, and I tried thinning Future a little. So, maybe it is just me, but I purchased and used several clear canopies and gave that one up. And, by the way, I tried stripping the unacceptable canopies with ammonia which is the solvent for Future but it left a residue. So... I would most definately experiment on a piece of scrap material before I tried it on my canopy, or have a spare handy. As a side note, Future, has a strong 'perfume-like' oder.

All the best!
