Chris400F:
I had a problem removing my seals a while ago so I posed the question on here, and got the suggestion:
"Heating the fork legs in the area of the seals with a heat gun and gently prying the seals with a metal bicycle tyre lever has worked for me in the past".
So I tried it, and my seals then came out pretty easily.

I tried a hair dryer and then screwdrivers/pliers/all sorts to try and get them out but they didn't budge. Do the seals have a metal ring through them or have I literally been cutting into the fork leg?
Chris400F:
They do have a metal core. which from your picture it looks as if you have been cutting in to.
I don't know if a hairdryer puts out enough heat. You couldn't use one to strip paint, which you would do with a heat gun.
I think you may need to go hotter to get the metal of the fork leg to expand enough to loosen the seals. Maybe someone else will confirm this theory.

I'll see if I can get my ancient blowtorch fired up then and just use it at a distance that doesn't melt everything
Jontyp:
I feel your pain on this one but the solution is more heat. There's nothing else to damage with heat except the seals and you're losing them anyway so have at it with a blow torch. I used a larger motorcycle tyre lever (has a perfectly designed hooked end just right for the job). Take your time, apply plenty of heat and they will come out (always assuming you've taken the wire retaining ring out first which it looks like you have).
Don't be afraid of using heat when stripping down old stuff (with the obvious proviso that you're not melting something important. It works great with steel parts stuck in aluminium (the seal inner ring will be steel) but even with the same materials it can be the best way to break a bond caused by years of corrosion.
