Nope. I didn’t use any of those vendors.
I did make one change in the install. Instructions say use spray foam around the cold plate. If you do that you will never get it out again if you have to. I used foam tape as in door seal to close the air gap around the cold platr. If I have to take it apart again, I can.
You could use Saran Wrap as a mold release, I suppose. I chose not to use the spray foam.
