Violet ★★★★★

Used this on the pump cup and O-ring before a cold-weather trip and the stove pumped smooth right away, no sticking. The little bottle fits easily in my repair kit too.

George X. ★★★★★

A tiny bottle goes a long way, and my stove's O-ring has stayed supple through a full season of trips. Pumping feels smoother now instead of that stiff grind I used to get on cold mornings.

Harper ★★★★★

Used a drop of this on the pump cup before a cold-weather trip and the stove primed way easier than last time. The O-ring stays supple instead of drying out, which was my main problem before. A tiny bottle but it'll last ages.
