Paint gun

Not with the gun really,the heat lopsided the lid enough that paint will just run out of the threads and create one he'll of a mess. I could not figure out what was going on till about the 6 or seventh time spraying the primer. After cleaning the lid would seal like it should with thinner in it! UNTIL like the seventh time and thinner went everywhere. The next day the lid returned to normal size. I called summit and got my money back.
