TurboForce, that is absolutely correct. It is impossible to perfectly touch up a scratch or scuff. I spent hours trying every conceivable trick to patch and match a couple of flaws. Impossible. You have to live with the scratches and scuff marks.
kram350kram, Thank you. After doing all the repairs, reinforcements, and surfacing, I shot a layer of black 2K epoxy by Kirker called "Enduro Prime". Filled pin holes, sanded and shot a layer of gray 2K urethane "Kirker Perfect Prime". Sanded then shot the final two (medium and heavy) coats of 2K single-stage urethane topcoat by Kirker called "Hot Rod Black".
Because of the inherent difficulty of shooting a box while in the box and the inadequacies of my home made paint booth, I had to do each stage of paint in four separate sections; 1. seat pans, 2. I.P, 3. Console and firewall, 4. Doors. My biggest battle was overspray and debris, not to mention the Kirker topcoat sheen varies depending upon the thickness of the final coat; too light-flat and too heavy-higher gloss level.
The fellows on the assembly line must have been driven to insanity. It is easy to understand why they did not paint the seat pans and speaker bowl in my car and also missed some areas and dripped in others.
