Where Thompson's Wins
Easier DIY application. Soap-and-water cleanup. Lower VOC (better for indoor sheds, near-house fences). Single-coat sufficient for most uses.
Where Cabot Wins
Deeper wood penetration = longer life (4-5 yr vs 3-4 yr Thompson's). Oil-based weathering pattern looks more natural over years. Premium product feel.
Application Tips
Both: pressure-wash 24 hours before staining. Apply in temperature 50-90°F. Avoid direct sun during application (dries too fast, won't penetrate).
