Pressure Pot Modifications/Suggestions

The pressure pot I am currently using is an old paint pot.  What I have done to ensure that it works properly is to use Teflon tape on the pot threads ,  I like the white tape.  There are several types of teflon tape.  Green/yellow etc.  It depends on the usage.  For my purposes the general all purpose white tape I find works the best.  The second thing I have done is I use a chain wrench to tighten my pressure pot lid securely.  Yes it has indents on the lid to grab, but I cant get a good enough grip without tilting the pot and putting it between my knees.  Doing that just slopped my mold around inside.  So having your paint pot secured is probably a good thing if you are using a modified design.
