As an oil-based product, it may have a longer drying time compared to water-based sealers, so you should plan for that when applying. Additionally, oil-based sealers sometimes require mineral spirits for cleanup, which could be a minor inconvenience. Its durability is solid for an exterior wood stain, but like many sealers, periodic reapplication will be necessary to maintain strong protection.

The natural cedar finish enhances the wood’s appearance while providing necessary protection against the elements. The drying time is reasonable, allowing users to get back to enjoying their outdoor spaces relatively quickly.

There are some considerations to keep in mind. The sealer is oil-based, which may not be suitable for everyone, especially those preferring eco-friendlier options. Moreover, it requires careful surface preparation; it should not be applied over painted or previously stained surfaces, as this could lead to adhesion issues. Also, the color may appear darker initially, taking up to 14 days to reach its final shade, which might not meet everyone's expectations right away.
