I've got to chuckle when you say you are a "production" guy, and it would slow you down. I will say that I do excellent body and paint work, but boy am I slow. I have had no training, and I have probably picked up a lot of bad habits that will slow me down. But I keep at it and eventually get the desired result. In the end, you would probably take less than half the time to get the same job done. But time is money.
