A while back while packing up to move, I had the brilliant idea of removing all the nozzles from my spray paint cans so I could move them without fearing that they would discharge without me present.  I am a bit artsy on the side here, so I have a whole lot of partially consumed cans of spray paint/etc.

This worked great!  Zero cans were erroneously discharged.

Just make sure to not misplace the bag full of nozzles during the move.  

The stupid part is that I actually transported them in a steel filing cabinet where there was basically zero possibility of them being discharged.

In any case, I decided that I was concerned about the noise the chain drive would make.  So began a multi-step process for soundproofing them.  

The actual soundproofing material contained acetone which would eat my ABS parts, so I protected my new chain covers with a coat of Plastidip first.  Then I went to work coating with bedliner... without a properly fitting spary nozzle.  Oof..

That is going to take a little while to dry.
