Anyone know about these two types of fixed portlights? They’re on a 1995 Beneteau 321. The top one is fully recessed while the side one protrudes about 1/4“. Both seem to have faux painted silver trim, so there’s no faceplate to remove. Each is roughly 8-1/2” x 26”. The other (opening) portlights on the boat all have access from the inside as well, but these do not. I’d like to rebed them since caulk looks old, but would like to know what I’m getting into before starting. Thanks.
