eracode: Scribers are generally used for bevel-back boards - not for rusticated boards. It’s not easy to find pre-cut scribers for BB boards that will exactly fit each individual requirement - the idea is to scribe and cut your own to suit.
Given that you have rusticated boards, you’re pretty much stuck with coverboards plus (a) ‘goo’ or (b) making and fitting your own plugs - or a combination of plugs and goo. It’s a bit tricky and/or tedious making plugs that fit each individual hole exactly and tightly - so go for a 80/90% plug fit plus goo.
This makes sense and is likely the way I will end up going. I think any soakers (if I could even find them) would not likely be large enough to cover... That said any suggestions for soaker suppliers for rusticated...
