Ahhh painting with Lacquerm and an Eldo convertible, both those bring back memories. A green 76', yep memories.
All I know is I painted it year round in a "shop" that was no more than a big garage. No heat, other than a home made heat lamp (six flood lights basically) and I made a living and fed the family year after year.
Now this was in the SF bay area where it goes from 40's to the 90's throughout the year.
