James, I've been dedicated to classic work for the past 15 years but was in the collision industry also. I'm no longer banging out collision work, nor will i bash it. I've been involved in the business since 1984, bought my first '68 in 1982 and rebuilt it on a dirt driveway. I acquire knowledge from many, including those in collision and classic car restoration. I call my reps to try new products and sprayguns, which they will do on the house. Also ask other pros for updates, and speak to numerous people in the business for product info and performance; which opens entirely new business opportunities.
Collision industry has changed dramatically. High strength steels have come into play. Welding and panel adhesive applications must be correct. I-CAR standards must be met. This is not like the 70's and 80's.
