A bit out of phase with my posts here - something to do with going off half cocked about rust :) The strut idea sounds great Paul if you can post or PM the details I look at that - my boot lid keeps hitting my head and I am worried about damage (to the lid not me).
Bad luck with the rust - good luck with the fix.

For gas struts google sgs engineering in derby they recharge struts or will supply new I got new boot struts for my 430 from them with a little extra pressure. They are happy to increase or decrease the pressure they put in and are very helpfull.
