Is it better to use an oil based product such as Chambers Traditional Oil Finish or Dem-Bart stock oil instead of Permalyn sealer as a sealer if these products (Chambers or Dem-Bart) are to be used as a finish. I read somewhere that if Permalyn Sealer is used the oil finish cannot penetrate the wood and the subsequent coats of oil would just build up and sit on top of the sealer. I also read that Permalyn due to its plastic polymer makeup is not as flexible as an oil during changes in temperature and humidity.
