I don't have a Simoniz, but my Husky power washer started leaking like
a sieve at were the nozzle connected to the gun part. Couldn't fix it
with a washer because of the shape, so I just put a bead of silicon
around it and screwed it back up. Fixed the leak fine, so far :) Also
look at their web site, you may be able to buy new guns for them.
