Cool ... on that white oak, notice that while it's more rot-resistant than alternatives such as red oak or eastern white ash, it can sometimes have a little bit of a challenge sticking to epoxy (vice versa). You'll want to sand and clean it right before applying epoxy ... 80-grit, ammonia, dry, vinegar, dry, then glue and install (or glass). Because white oak 'might' have an issue with epoxy sticking, I'd hedge your bets and glass the aft, straight, Prince Rupert type spray rails. You can probably get away with pre-glassing these since you won't be bending them around the forward half of the boat.
I assume you're referring to the aux. spray rails along the forward end of the chine? If you glass first, it'll greatly stiffen up the wood and make it difficult to install. Glass is very strong and unstretchable in tension. If you want it glassed and bright-finished, install it first then glass it with 4-oz or 6-oz glass .... it disappears in epoxy and looks like there's no glass there, yet is still pretty durable and abrasion-resistant.
When you patch screw (or other) holes after installing rails, mix sawdust from similar-colored wood. The sawdust will turn darker when it's mixed into the epoxy, but silica lightens it back up and helps it stay in the patched holes. Fill them proud then carbide-scrape them smooth after they're at least mostly cured. This is for bright-finished wood of course.
