Although I'm not finished, I feel like I've made good progress. Here's the latest.
Rockers, inner fenders/inner quarter panels, door/hatch/hood jams, fueling compartment, trim pieces all have received 2 coats of epoxy with no problems.
Outer body panels all have one coat of epoxy, but temps were low and my gun leaked, so I wanted to do some more sanding. As such, I've used the finest grit I have at the moment (220) to level the surface again before applying another coat of epoxy. I've only done 30% of the car and so far I have no burn-through.
Here are my questions:
1-On panels with no runs, should I skip the 220 and just go with 400 before sealing the entire car or sand the whole car in 220, epoxy the whole thing again and then 400-600 and paint?
