We have been using most every system available over the years, but keep returning to the Polyfibre line for its ease of application and longevity in the field. Highly recommend Polyfibre Products to anyone from the novice home builder to the professional.

Everything great. Only complaint? Previously I tried to buy MEK only to learn its crazy high price. (plus shipping of course) Months later I found Ace Hardware was again stocking it, but only in 5 gallon cans. No shipping to local stores made it, at $99.99 a good buy except that I dont need more than a gallon. I got a flying buddy to go halves with me. Now we bot have a years or more supply. Ive yet to learn why no retailers carry it. Only a substitute. Baloney! Even my congressmans office could not find out. Is it fear of lawyers, or some obscure and insane environmentalist law? Ditto for Plio Bond. Only green substitute at a higher price. I dont buy substitutes. I did find the real thing at another supplier---no problem. Turns out as Virginia goes Blue---following California and Oregon, its northern counties only join with the Northeast and a few other states in prohibiting it. I couldve asked further of Aircraft Spruce but I was too angry at you! The Aviation community must stop buying into the insane, global communist effort to strip us of our property and living rights under the guise of saving the planet! It is, next to the fake attempt to impeach Trump, an effort to turn us into another Venezuela or Cuba! Weve already cleaned up 90 percent of some of the admittedly wrong pollution of the planet. No, it is Earth that God gave us to subdue and develop for our use for our salvation. Of course we must care for it and not waste valuable resources. That is good stewardship. The best way of cleanup now is to dump half of government and its abusive rules and taxes that force us all to work harder to stay where we are. Forget about getting ahead! Dont forget inflation, the most abusive of our environment taxes. Keep up the good work, just fight back! Mike Smith Chase City
