IMO, no such thing since it just takes alot of practice, tril and error approach. The more material you have for pictures and inspiration the better though. Heres some suggestions.
Book: How to build the Misserchmitd 109 (paperback, covers most kits, scales, painting/weathering, as well as flaws). Theres one for the P-40 also, check at local hobbyshop as I've seen this book around alot.
Check out Hyperscale and Verlinden magazines, great inspiration there.
Scale Aviation Modeler is the magazine to subscribe to if your active in building.
WingMaster, a french model magazine is also excellante but its in french. Good pictures.
yes, 109 cockpit was blue/grey RLM#. I would recommend getting a copy of the Testors Model Master paint catalog. Its free at the hobbyshop near the paints. Its got an index of all the paint chips of colors they make. Good to use that as a basis to compare colors between brands.
>Masking tape.
Tamaya Masking tape, thats the best paint tape for models. Also youll want some liquid mask like Mr Mask from Gunze Sango. Use both if you have to for cockpit frames, whatever works best. Always cut masking (paper/liquid rubber) with a fresh or very sharp blade. I personally use a regular Xacto-knife for building then switch to the disposable testors-razor for masking. Testors got the sharpest razor blade on the planet.
>Dull ruined canopies:
You can also get a bottle of "plastic/jewlery model polish" and polish out clear plastic parts. Use Elmer glue to glue canopies (no fogging) but fit has to be good.
enjoy...
