I am about the sole responder to questions on the Citristrip Ask The Experts board. I don't work for Citristrip to get any remuneration from them. They do send sample if I ask, which I have done once. If I don't like one of their products or know of a better product for a particular application, I will say it on their board. But I do like and use some of the Citristrip products for many uses. I have also used Peel Away 1 on old wood with about 20 coats of paint and been happy with the results.
