Hi Both,
Many thanks for your thoughts! I think my problem is the gate at deck level rather than the foot – althought I will try to check this on land at the weekend.
Think I will try candles first – easy and cheap! Hadn’t heard of ptfe sheets/film so that’s a useful idea to have as back up – thanks!
Did some more googling after posting last night – other possible options I found were graphite spray/powder (for locks) and ptfe spray – anyone used these?
Cheers,
Keith
