Actually it's called Eze-Kote Swanee, from Deluxe Materials 😉
It's not the cheapest resin but it's quick and effective😊
On untreated wood I sometimes dilute it with about 15-20% water so it soaks in a bit.
It raises the knap which you can then easily sand off.
Then I apply 2 coats of neat resin to seal and strengthen.
Helps protect from knocks and bangs💥💥
