If all else fails, a hairdryer is a good tool for shelf divers. (Heat up the vinyl to restore the 'memory' of the original shape.)
A few days after my post above, I was going to realign my snotblower with a hairdryer. I noticed that the reason for the lean was the last tail segment was loose. I pulled it off, re-glued it with zap-a-gap and hung it upside down by the tail end so it would dry in the proper position. My snotblower once again has correct posture.
Received my first Snotblower yesterday (copper version) and its great. The detail and build quality is fantastic. Got offered a 'Bloodwipe' yesterday too so thats gonna be on its way soon to make a pair. Gonna need to keep my eyes peeled for a Verdigris version now too.
