As a person with Multiple Chemical Sensitivities, using paints, stains, sealants, etc… has often meant being ill from fumes and contents. Aside from the fact that Seal-It products work really well, the major plus is, for me, that they do not trigger migraines, nausea or asthma attacks that would plague me around other products. I can handle the material and the skin on my hands does not crack and peel. My partner is a Seal-It distributor and I often help him with the materials ~ packaging or preparing the sealants for sale or for application, clean-up of tools, preparing sample sized products for demos, using the products in our own lives ~ and I can honestly say that I have yet to have a reaction to any of the products. It has been a real challenge to find products that work thoroughly and efficiently without making me ill and I’m happy to say that Seal-It makes that grade.
