Another Mopar Off My Bucket List - Barracuda Fastback

As I finished putting the fifth coat of varnish on the wood I noticed some slight curdling along some of the edges. Why it's doing it on this final coat and didn't on the others is beyond me. This last coat is unreduced. The layers beneath mean that there is a heavier build up of varnish than before. I'm hoping that these flaws will vanish as the varnish dries. If not, I'll have to sand and repair.

The wood for the sides of the box warped from exposure to moisture without having a protective finish on them. I cannot simply sand and apply varnish to those pieces. I searched online for repair methods and am hoping that I've found a solution for the warped planks.

I read that applying moist towels to the cupped side and driving the moisture into the wood with an iron will help. The second step is to apply dry heat to the convex side of the wood. If it doesn't work I'm supposed to repeat the process while clamping the wood down to a flat surface.
