Most motor shops if big enough do coachlining on a roll, it's simple if you
use a chalk or crayon line as a guide and you will need to carefully peel
off the old one and give it a good cut polish as the paint will be at a
different level.

to get the fancy ends is easy as you lay the bottom line first and then get
the thinner top line to join it at the end.

The old way to coachline was to use a roller mechanism that hand painted the
pattern or of course for a true diy invest in some dagger brushes.

On old Fords I used to mask off a pair of tramlines and spray with either
silver or gold autopaint, looked good.

Charlie Browns usually is the best bet for coachworking and graphics and
some of the bigger outlets have workshop facilities so may be able to do it
for you otherwise its a paint and spray specialist which will charge a few
extra quid but will provide the best finish

I used Herts Signs who are based in Hatfield - only a short distance
from North London. They made a superb job of replicating the original
shape and colours of the Jag coach lines, and at moderate cost. Having
seen them apply the stripes, I know I could never have matched the
finish without a lot of practice.

Cars which have non-original stripes, as from a car accessory shop,
stick out like a sore thumb in my opinion. And the 'proper' Jaguar
stripes are an absurd price if you have money to burn.
