This is my first post in this forum but i have searched and can't find an answer to my problem.

I'm stripping down a set of 993RS speedlines and i've removed all of the bolts and the centre piece but can not separate the rear dish from the front lip due to the heavy duty silicone sealant which has been applied (presumably at and earlier refurbishment).

I have tried cutting through the sealant with a blade but there is too much in depth and it must be also between the faces of the rims (behind the bolt holes) acting as a glue. I feel that if i can get enough off then i should be able to separate them by sliding a blade between the faces but i need help getting to that point.

So, after that long wided start, is there a way of melting or softening the silicone sealant by either heat of chemicals to allow easy removal? Or does anyone have any general tips (bar the obvious that i should have left it to the pros - i thought this would be a good learning exercise

How about using a heat gun?

There are compounds available that break down the bond between silicone and other materials. I used it when I had to do a similar job on my RH Alurad 3.6 Turbo wheels.
I tried WD-40 at first to soften the silicone, but that didn't do much. I did a web search and found a company that sells a compound called Digesil NC.
It is sold by a company called RPM Technology out of New Jersey, here in the states.
Try www.rpm-technology.com. The stuff was not cheap, but it did work. The gentleman I talked to was James H. Esposito. His number is 973-463-1386.
He might have some type of contact for the UK.
Good luck.
