Help, I screwed up my b-25b nose cone!

I am building a b-25b Doolittle Raider for a huge diorama. I used the future floor polish trick and dipped all my clear plastic in to a cup with future. It all turned out great, untill I cleaned up the nose plastic, and attempted to do it again - it came out horrible, was foggy and now has a white ghost ring around the colar look where it is supposed to meet the fusilage - how can I strip future without harming the plastic? I am on a deadline, any help would be greatly appreciated !
