Hi guys
Latest quandary for me is that the paint finish seems a little vulnerable. (It feels "Not as Hard" as I would expect.)
Is this just my perception - or should we use a sealant coat as we would in the automotive applications?
I am using Interlux Brightside Yellow - which apparently requires 5 coats instead of the normal 3 coats for darker colors. (I can attest to this as I am still showing shadows after 3 coats)
Regards DuncanB

Yes, the yellow does take an extra coat or two, at least it did on my SUP, especially because I used some fairing microballoons to fix some epoxy screwups and it is a dark purple color against the pale okume ply.
Brightsides seems to take a long time, like weeks, to reach its final hardness. Once there, it is pretty good, but face it, drag it over sharp rocks or a concrete ramp, and you will have to do some scratch repair. Even a clear coat wouldn't prevent that. I did find out on my skerry that the Prekote primer really isn't the ticket. It's soft and if there are any areas with more than a tiny film of it, they make the finish on top softer. If I had it to do again, I'd have sanded more and put Brightsides right on the epoxy. That's basically what I did w/ the SUP, using the epoxy/fairing mix to deal w/ some of the surface faults instead of the primer. Better hardness.
