I have a leak in my window washer tank... do i have to remove the tank or can it sprayed directly into the tank? or would it just leak out? a real pai

depending on the leak, I don't think will do what you want. Permatex does offer a plastic tank repair product that will repair your leak. here is the link to the product here on Amazon. https://www.amazon.com/Permatex®-Plastic-Tank-Repair-Kit/dp/B0007TQWM4/ref=sr_1_1?crid=D6ERNWY9KSY2&keywords=permatex+plastic+tank+repair+kit&qid=1576547881&s=automotive&sprefix=permatex+plastic+ta%2Celectronics%2C164&sr=1-1 I hope this helps

I have a pinhole leak in my transfercase, it gravity drips maybe a couple drops an hour, will this work?

You have to drain the case, spray with brake cleaner and lightly sand around the hole. I applied JB Weld first and then sprayed this over the area expanding out past the actual hole by a couple of inches. The combination seemed to bond better to the metal. If the hole is small enough and you get it good and clean the spray might work on it's own. I just went the extra yard because if it didn't hold I had to start all over again. Good luck.

will it work on a gas tank leak

No, the gas tank pressure is too high for this product to stop the leak.

does it work for high temp areas?

worked on a vw pushrod tube seals on the block but had to give it several coats
