Ideas needed for brake line thermal wrap

[rhock99 at epix.net (Ryan H)]

ok guys, finally bent my new passenger side (hard) brake line, and well I was off by a little... I ended up with about 8 extra inches of line!  Anyway, it works, but now the line sits in FRONT of the little shield going across the firewall, instead of behind it.  So I need something slim to wrap around it to keep the exhaust manifold heat out.  Ideas?   I don't know much in terms of thermal wrap / insulators...
