hmmm regarding above post.
Id try RK in osbourne park. 0428375973.
he admits to not being the best painter, but will fix and cover, then you can do what you want. I just touched up and stickered my last repair after he sealed up.
Possibly the best with finplugs/boxes.
RK just did a repair on my channel bottom (side fin plugs) and was spot on, couldn't be happier.
