Removing the foam from inside a fairing

[Linkex]

So if you read my other thread, you'll know I dropped my Ninja a few days ago. The only damage in terms of rendering the bike inoperable was the right hand rearset, and I have a replacement on the way. So I decided to have a go at repairing the RHS fairing with fiberglass. I got a kit for £10 from halfrauds, so if it dosen't work, I'm only out a tenner and will replace the fairing.

So, I removed the fairing from the bike and used a hairdryer to take all the decals off, but on the underside is a lot of foam padding (I assume heat barrier/sound deadening?) It needs to come off so I can get to the damaged parts from behind.

So, the question is, is there a way that I can take the padding off so that I'll be able to re-attach it after I fiberglass? I had a go with the hairdryer and it didn't seem to do much, and I don't want to use a solvent remover because I expect it will damage the foam, and if it doesn't, the foam may absorb it, making reattachment impossible. The only thing I can think of is to use a plastic blade and run it underneath, trying to preserve as much foam as possible. Is this the best way, or can someone suggest an effective method for removing it?

Actually, it was pretty easy in the end, probably because the bikes and therefore the glue is old. I went to Dunelm and grabbed a plastic palette knife. Lift up a free bit, and slide the knife into where the foam meets the fairing:

Should have video'd it, cos its hard to explain, but basically I was tapping the knife against the foam quite gently, so it was only lifting half a mm at a time. It took about 30 mins, but in the end the foam came off in tact and I was left with just the fairing:

It'll need a good clean with some kind of solvent to get the rest of the glue off (Any recommendations?) but once thats done, it'll be ready to fiber glass.
