Might be sensible to also get a quote from Ventureshield as a comparison What is VentureShield paint protection film? | 3M Ventureshield I had the ventureshield on both my Multi's
From memory, I paid about £120 for my kit, 4 years ago? Pita to fit, but worth it, as it does save the paint from chips and boot scuffs etc.
I do the odd bit of DIY but fitting film to a complex curved surface - no thanks!! That's a job for the pros in my book.
It was £225 including VAT and fitting back in Feb 2013, that was on a 2013 Multi and included the Panniers. I had it done before I collected the bike.
