Jesse,
These wet wood, throw it on and go type stains have come and gone in the past 8 -10 years. This is not to claim that Everett's stain is not to be used, but the track record of other formulations is not positive.
I was at Everett's location 3 or 4 yrs. ago when he introduced his stain formulation to a group of contractors. My only impression was the resulting pigment after application was not attractive. But then again, it had just been applied and had not cured. Kind of looked watery!
How bad is the typical rain pattern in Western N.C during wood season? Here in the Northeast, yeah, we get a fair share of no stain days. We just learn to work around them. We have been using Ready Seal stains (a paraffin oil based stain) going on 13 years now with great success. Jake's (Armstrong-Clark) stains are also very well formulated and manufactured, being a hybrid of paraffin and linseed oils.
