Get a new Mars. Blackburn lifetime warranty is handled through the shop you bought it from.
This, I've had a rear flea replaced by CRC but the second one died too and I'm now using a Mars 3, managed to loose my old Mars so just replaced it with like for like. Try taking the Mars apart and putting some silicone sealant on the joint then putting it back together should waterproof it a bit better
