So I typically wait for 6-8 weeks (as I run late on time) between the last coat and wet sanding (wonder if thats part of the problem??). I've tried various things, the latest I've got Stewmacs medium and fine polish which I apply using a foam pad in a drill, then a meguires swirl remover with a hand held foam pad. To get off any dried polish I've got a pile of rags, the latest bunch is from a nice well worn winnie the pooh winter sheet - perhaps not soft enough?
Yeah, I've been back and forth on the screw thing. So I've had issue with cracking when drilling new holes, even when running the bit backwards first to wear the finish etc. The latest I've tried is countersinking all drilled holes and running a drill bit through before 2nd to last coat while everything is still real fresh to remove as much as possible. That seemed to work mostly ok. and then using heat on the surface before installing screw - again soften the surface.
I'm trying to install most of the bits on guitar before finishing to check alignment and make sure everything will work. Easier to plug and redrill holes before finishing!
Have heard about the wax trick, should probably do it rather than risking it by just wiping the water off!
Wonder if I should try Mirotones nitro and finish with the same system I always use to know if its technique or product. I see that Timberly wood turning offers NC in 1L tins which they "decant of large drums", so I wonder where they get it from...
One day I'll get it right..... Unfortunately with the cold weather, I might have to wait a while.
