Cheers guys....much appreciated. Don't think the temps are going to get anywhere near close enough to make it work!
Like the idea re hot water. Will probably use that BUT will now be doing the work indoors in a partially heated workshop.....sadly not my own!
I fitted a "Keelguard" a couple of weeks ago (bought from the states for a cracking $110 and brought over by my little Bro RESULT). Did it at a friends bodyshop with heaters. Really warmed them up before using and applied a heat gun when fixing....amazing how much easier it was to work...would recommend.
