Brushed on the 2nd final hotcoat - it looks really beautiful. I’d not even sand it but I have to for the Future boxes and some slight surface dust. Start with? 220? 320? 420? I’ll try 220 for the boxes only, if I can do it without knocking the surrounding surface. What do you think??
Let FULLY cure!
Choice of grit is not set in stone.
Lotsa sanding, use grittier.
Just cleaning the dust specks, maybe 400.
Kinda like hitting a baseball. You can’t ask over the internet how quickly to swing, since it depends on your strength, batspeed, weight and length of bat, how fast the pitch is coming, and from where.
You gotta BE there to take a look and make the judgment!
