Not planning on floating them, they will be stapled at an angle in the groove just like regular wood floors every foot or so. Not planning on gluing at all, although I may do something in the seams, haven't decided yet. Only the first course will be affixed with adhesive and face nails.
I have a pile of it right here to test with :D
Honestly, I've used a plane maybe twice in my life and I don't own one, nor a card scraper. I'd need solid suggestions on what to buy (Amazon links?) and it can't be more than $50. Maybe a few youtube video links as well on how to use/sharpen. The scraper I'm looking at is this Bahco.
If it's dry use a card scraper to take it off.
