You buy a board to SAIL so sail it.
It's all about freedom and enjoyment.

NOT to agonise and worry about it, wrap it all in daggy plastic thingos, knobs deflectors etc etc

I mean you wouldn't wrap your car up to avoid a ding
You're an experienced sailor, but the odd ding happens to all of us
Buy some epoxy glass mat and Q cell $50 will set you up for life
Chek out the Board Lady site (or Mark Aust will tell U anyway

)
And with your artistic flair I'd say you'd get a far better finish than most
