Looking good Ryan... be sure to post the finished product. I'm basically in Hampshire (Basingstoke) - where did you get it done?
A BIG word of caution. I had a beautiful paint job done on my 400F bits, and like your tank, the Yellow was taken right the way up the filler cap. Within 60 miles petrol had wicked under the paint & down the sides... amazing because the top lacquer was bone dry.
So, the tank's be re-done, with the yellow only 1/2 up the filler, thence fuel resistant lacquer the last 1/4 inch.
Take care!
Simon
