OK, I have screwed up big time & need some help.
Over the weekend after the lens cap falling off my
70-300 lens yet again, I decided to put into action a plan I had come up with earlier last week. I had a spare UV filter that was scratched, so had no use for it. My idea was to super glue the lens cap onto the filter, which I can then take on & off the lens by simply screwing / unscrewing it. Simple I thought & I don't have to spend a penny.
Well yesterday whilst watching the footy I decided to give it a go. I had decided to put the filter on the lens & then glue the cap to the filter, that way I would not get any glue on my hands etc. I even put newspaper in the dining room on the table to stop any mess. What could go wrong !!
I had the lens, the filter, the cap & the super glue. I was ready for action. Just as I was about to start I could hear people cheering in the lounge. Someone had scored, so I leapt up to go see the action. After 5 mins I returned. I put the super glue on the lens cap & fitted it to the filter on the front of the lens. Perfect !!. I felt really proud, until I caught the sight of something on the floor by me. IT WAS THE FILTER !!!! . In all the getting up to watch the football I had knocked it off the table. When I returned I obviously didn't see it on the table & must have assumed I had fitted it

I HAD ONLY GLUED THE LENS CAP ONTO THE LENS DIRECTLY
Now I've tried everything to get it off to no avail.
Can anyone advise of anything that will melt the superglue ? Will boiling water or white spirt work, or would this damage the lens ? My wife bought me this lens as a present, so will go ballistic if I tell her what I have done.
I blame this all on the world cup
