Bruce - 55 sounds good for painting and getting it to flow. But...I thought Zero and others need to "cure". Does it need to cure at 55 or will X (4 or 6, etc) hours at 55 do the job and then let the temp go colder? It would be difficult to keep my garge at 55 for several days. I need to figure this out asap as I only have about 5 weeks before the body goes back on.
