I'm currently testing 3 finishes on a piece of scrap:
Behlen's 100% Tung Oil
Formby's Tung Oil Finish - Lo gloss
Minwax Tung Oil Finish
The directions of each for between coat treatment is different:
Behlen's -- scuff sand with 400 grit sandpaper
Formby's -- rub lightly with 0000 steel wool
Minwax -- nothing
What is Behlen trying to accomplish? I thought scuff sanding was to
get a new coat to stick to previous coats -- which doesn't apply to
non-building finishes like 100% Tung Oil.
What is Formby trying to accomplish with the steel wool? I thought
that was to adjust gloss after the final coat.
I'm tempted to follow Minwax's advice and do nothing between coats
(besides wipe with a lint free rag to remove dust).
Thanks for your thoughts
