Cracks along non-skid, how to fix
So I bought a boat which has a series of perhaps 8-10 four foot long cracks around one stanchion base, supposedly from buckling when some unhelpful dock person pushed on the stanchion to stop the boat.
Everything I've read says to open the cracks with a sharp edge, such as a cabinet scraper, fill the cracks with gelcoat paste, then sand and fair.
Obviously, that assumes a smooth surface to fair to. But what if those cracks are on nonskid of the sort built/molded during layup (e.g. not painted nonskid)?
How would you go about fixing that and at the same time keeping the cosmetic appearance of the existing nonskid?
