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

Atende a expectativa.

Produto resolveu um problema entre a calha e a parede evitando escorrimento de água da chuva mostrou-se mais eficiente que o veda calha. Esperar para ver a durabilidade do produto sob as intempéries.
