What's the problem with the paint BB, and what type, enamel or acrylic ?
I've rarely stripped paint when I've needed to 're-do' something, as it can clump together in horrible sticky lumps, particularly around crevices and angles, so I normally do a rub-down, prime, and start again. But, it can be done. One method I haven't tried, but believe works very well, is to use 'Mr Muscle' oven cleaner, on enamels anyway.
Before you try anything, post a pic, and a description of what the problem is, with as much detail as possible about the type of paints, how it was applied etc.
The good thing about the Mossie, is the overall smooth surface, with relatively little surface detail, so hopefully that shouls makes things a bit easier, even if the paint is a real disaster and looks like a Hippocroccofrogs *rse !
