Is thinning regular off the shelf polyurethane 50% acceptable for use as a wipe on finish? The directions have an all caps warning not to thin. VOC related?
Wipe on poly.

Probably for VOCs. I've thinned Arm-R-Seal successfully on numerous occasions. Wipes on nicely.

#3There are more than numerous posts/articles about making your own wipe-on poly by thinning regular poly, However, this seems to apply to oil-based poly rather than water-based (WB). Some do make water-based wipe-on but I think their dilution is much less than 50-50 since WB is thin and dries fast already.
Thinning does not allow the product conform to the label description such as number of coats, drying time, etc. which may be a reason that it is not recommended or are you looking at WB poly?

#5I've been wiping on unthinned Minwax oil-based poly right out of the can for years.

I've done this as well when doing trim.

#7While it isn't poly, I use undiluted LV polymerized tung oil as a wipe-on finish all the time. Lots of turners do. The do sell the same product pre-thinned but label it as a "sealer" presumably because the thinner mixture gets into the grain/pores easier.

It's sold formulated for wiping on.

#9The Minwax poly labeled "wipe-on" is $5-6 more per quart. The regular version works just fine for me.

#10The cost for the pre mixed poly was double than the regular. I had the thinner already. Two coats of the 50/50 on now.
