What's the difference between Penashield & BoraCare? Especially since Boracare is diluted?
Is this 'already diluted' Boracare?
Penashield and Boracare do have the same active ingredient. However, Penashield should be used every 1-5 years while Boracare lasts for the life of the wood in favorable conditions. We would recommend using Boracare if you are seeking a longer lasting treatment.
