Thompsons water sealer is about the worst junk going. It is useless for anything and everything. The reason is simple and explains the low cost; it is almost all solvents. The solids are scarce and do little to actually seal anything. KA outlawed early formulations of the stuff because the Volatile Organic Compounds (V.O.C.s) level was so low. For the low end target consumer the stuff seems great; it applies easily and looks good for at least 15 minutes...

Solvents are designed to make application of finishes easier. They never improve the final product aside from flattening the surface and increasing penetration.

The sad news is all oil-based finishes are very much alike. The better ones use less and better solvents leaving more finish solids behind than the cheap versions. And oil finishes absorb atmospheric water faster than bare wood.
