Check it out for yourself.... Look through the threads here and pick a few formulas recommended.... Do a few samples and let dry thoroughly. Then take a hot shower with the samples getting a reasonable dose of abuse. Let them dry in the hot sun all day and allow them to set out overnite exposed to the morning dew. Then put them in the refrigerator for a day before putting them on the picnic table laid out as a covering, invite the guys over for pizza & beer, carfully spilling the sauce and beverages evenly, allowing them to soak in before rubbing down with lambs wool and hosing down with harsh detergent. Carefully carry back to the shop and examine which ones stood up to typical customer's expectations, and typical craftsman's claims about durability. Now you will be qualified to speak at community college evening classes on "Achieving Professional Results with Finishes You Can Make at Home". Then write a few articles and a book. We will all be cheering for you when you go on Yankee Woodshop. Need a manager or public relations exec???
