Foil care: rinsing, anti-corrosion gel and avoiding seized bolts

Posted by WingFoil Admin on 2026-10-21

A seized foil bolt can end a session or a trip. Poole Harbour Watersports has a simple care routine that covers most problems.

Key takeaways from the Poole Harbour Watersports article "How to look after your wing foil kit?": • Rinse the foil and bolts with fresh water after every session. Salt and grit slowly corrode threads and inserts. • Apply anti-corrosion gel to the bolts before first assembly. You do not need it every session, but it makes assembly and removal much easier. • Dry the board fully before bagging it. Trapped moisture can cause small osmosis bubbles, and leaving the bag unzipped helps it air out. • Keep board, wing and bag out of long direct sun, store them cool and dry, and rinse the wing to protect its seams. • Assemble the foil on something soft (bag, grass, sand) and watch for rocks and docks when launching and landing. • Check regularly for cracks, dents and loose fittings, and fix small issues early.

What's your post-session routine for the foil? Ever had a bolt seize, and how did you get it out?
