Love seeing this being brought back to life! Keep the updates coming.
As an aside, how would one go about acquiring a workspace like that? Looks perfect!
Great work on the car as well!
Cheers!
Is the Raptor a textured finish? It looks textured on the jig pics. I thought it was a smooth finish product developed for truck beds. Looks great though.
I was thinking of getting a small Propane space heater
As long as you're prepared to accept that propane will introduce moisture to the air.
Some heating options: woodstove, waste oil heater, reverse cycle air conditioning, electric exchanger for central heating.

Waste oil heater sounds worth investigating.
