Can you use this Flex seal too caulk around your window frames? (more like a insulation)?, or stop a small draft creeping thru your window pane?

I'm sure you can. I have a waterwheel and trough. I sealed the trough, as it was leaking in several places. Even though water runs rapidly down the trough, I've had no leaking now for 2 years. I also used it to seal a leak on my ATV tir rim. The rim had a slight curve and wouldn't hold air. I sealed the sot that was leaking and it worked perfectly.

I have a leak in my car trunk, can this be used?

It really depends on why there is a leak, but probably not. If it's the weather stripping around the trunk (that rubber tubing stuff), I doubt that this stuff will replace or repair that. That's the most likely reason you have a leak. The seal needs replacing.

Can it be used on concrete?

Yes you can use Flex Seal on concrete.

I would like to use this to refinish and seal up a mobile home bathtub. Does it clean easily? Will it hold up to the constant use of a bathtub?

It will definitely seal and refinish the tub. I’m not sure about easy clean up as I only used it on a boat but it should clean up nicely as it seems to be self leveling spray and is very smooth when completely cured

It really works well.

This stuff really works, I used it on a big cement water fountain that was no longer holding water, it holds water again, good stuff.

Protective for outdoor items

I've used the clear coating a couple of times on my outdoor lawn wagon to protect from the elements and other items that might sit out in the weather occasionally. It really helps keep them from rusting, scratching & deteriorating as quickly so it's worth it for me.
