You may or may not know this.
finishing up a 109 the canopy required painting so
I dipped the Canopy parts in Future masked up and sprayed.
When I removed the tape There was a vast amount of bleed.
As I had a spare I decided to see if I could clean the clear parts up,sprayed with oven cleaner.,left, scrubbed , rinsed and crystal clear parts resulted, to start again.
Hope this is of some use
