Your Welcome, I have never worked an area as large at one time as your doing, Working alone on that large of an area means you certainly have to have everything laid out perfectly to come within the kickoff on the Epoxy. I recored the coachroof on my Electra and set too much weight on it and bowed the roof in on both sides of the hatch. That sure caused a lot more work than I originally planned on, so I understand learn as you go very well.
