I picked up a couple of french Oak wine barrels that i wanted to use in the man cave, but prior they lived outdoors and have some obvious wear. Not necessarily looking to make it furniture quality, but give it a little shine without so much elbow grease.
Can any wood workers out there recommend a product i could use to accomplish this?
Figured it would be something like that. I was looking more for a "1 and Done", but have a feeling they will look 10X better doing it the way you suggested. The tricky part is going to be not ruining the cool bark rings that sit over the metal bands.
I wouldn't go with anything too coarse. If it takes a little longer with a finer grit, I'd say it was worth it. I'm gonna estimate a 200 grit, because you just want to remove the weather-worn wood fibers, not smooth the entire exterior.
