Sikaflex:how to remove it?

Just removed a transducer from my SR's transom.I am left with a large slab of Sikaflex which doesnt want to come off.I can scrape it of course but this also scores the gelcoat.
Is there any product which wont damage the gelcoat & which will break down the Sikaflex so it can be removed easily?

No, although heat can sometimes help

I found it comes off if you rub it hard with your thumb or finger (that sounds really dodgy, glad I'm not going to reply to his post!). It's very slow going though.

I tried that with a rag & it does work but its seriously slow. I thought my arm would drop off or the transom would go on fire from the heat generated by the friction!
There must be something that will degrade Sikaflex / cause it to break down, the area I have to clean up is about 25" square.

On my last rib I had to get a load of Sikaflex off that had been used to fix down a jockey seat, it took three hours using a hear gun and my thumb, safe to say my thumb took a few weeks to recover.

Took me back to school days again

I've done it myself but with out the heat. Once one thumb got to much I moved on to fingers, then sides of hands.

Yea it was on a backing plate, a bit of overkill but it came on the boat.
