wiper fluid leak update
 

Just an update. I finally found the Permatex epoxy and it does stick
the the HDPE, thanks to merril for the tip. The problem is that the
leak is from a seam in a spot that is very hard to get to (bottom of
the molded mounting rail). It looks like it will have to be sealed
from the inside. Since the leaking spot is invisible to the eye, I am
considering sealing with roofing tar, silicone or maybe radiator stop
leak. Any preferences?

Thanks

I wouldn't use anything that could get back into the system. Especially
stop-leak. Who knows what the other stuff would do.

Just take the tank out, fill with water and some food coloring, find the
spot. If you have to drill it out a bit, do so, then fill the area with
epoxy.

Epoxy does *not* bond to polyethylene. Permatex does not claim it does:

Permatex is swindling you with the packaging suggesting that
it works on "plastics", which in fact it only works on a select few.

On the back of the package it says it may not bond to this plastic but
it seems that in practice it works well; I tried to scrape it off and
could not and it has stopped the leak (put it on the inside last
night). Another member of the group has also used it and it worked
for him too.
