A Question.. On frame protection kits

[sli0ch]

Hi folks,
just a quick ask really, I'm riding an XL alloy 575 this is a bike it pretty much took me 20 years to be able to buy so obviously it's my pride and joy, and I want to keep it as nice as possible as long as possible,... With that in mind I'm after a recommendation for a frame protection kit, ideally clear 

Thanksin advance

Thanks Andrew, that's kind of where I was headed.. Although they don't do an XL kit for the 575, but have offered to add in some extra material for me to make my own
