For anyone else thinking of replacing their fork seals but is apprehensive this video by Delboy is brilliant:
I also made my own spring compression tool:

A couple of tips: 1. Make sure you lube the bush and fork seal prior to fitting 2. Tie a wire or piece of string around the damper prior to re-inserting the spring as you will need to pull the damper up to attach the fork cap.
The only tool I bought was a fork seal driver as I didn't want to screw that bit up!
Laser Fork Seal Driver = £40
2x OEM Fork Seal & Dust Cap = £56
2 x 10w Silkolene (RSF 10) Fork Oil = £27
Total = £123
Satisfaction of doing the job myself = Priceless!
