Heard through the grapevine that Guse Hardware on 46th and Bryant in S. Mpls is selling epoxy wood filler from Advanced Repair Technology. Stopped in today and discovered that indeed they are. In fact, they told me they are the only outfit in Minnesota selling these products.
Now why would you spend hundreds of dollars on wood filler when you can buy any manner of products for just a few bucks? The answer is really quite simple. If you want to re-do your window restoration project every couple of years, go ahead and scrimp on the wood filler. If you want your restoration work to last, invest in a quality wood filler like the ART epoxy, or WoodEpox from Abatron.
