Can this be removed if need it?

Not easy but yes, by sanding and grinding

Would this work on a leaky pontoon where there is an area that looks to be a little corroded?

I think it would if the area isn't too large. Would be a good temporary fix.

will this work on aluminum motorcycle engine case ?

Not impressed with this stuff. Tried to stop a leak of trans fluid didn't work as soon as it got hot. I wouldn't use it on my bike.

Don't think there is a cure. 24 hours exposed to air is what I have gone by. Slow, but it is strong when finished.
