What's your input?

I used the spray in an attempt to fix a leak below the windshield of a car.

Because of limited access to the specific area where the leak was occurring
and the amount of rust in the area I was trying to seal, I was only able to
improve the situation, not completely stop the leak.

The best I can say is that it appears to work, but since I couldn't actually
see the entire application area, I can't blame the less than perfect results
on the product. I don't know if I was able to achieve 100% coverage, but the
leak was reduced by a considerable amount.

If the only allowable answers are "Yes, it works as advertised" or "Run away
as fast as you can", I would choose the former.
