Red colour

Its a Candy Red, a red varnish sprayed over a silver base, to replicate it properly you need to follow the same method and not use a modern Metallic Red.

It was used on quite a few Brit bikes, trouble is the process means it varied from bike to bike, the number of coats of the red varnish being one variable.

CandyAppleRed(As used on the late G80CS and other Matchless and Norton of the same vintage):First of all, this color is correct (sic) for the very last short stroke G80CS machines, that beinglate 1965, 1966 and 1967. Contrary to some popular opinion there were no G80CS'smanufactured in 1968. There were several of them that were titled and sold as being 1968machines, but that is an entirely different thing than manufactured.My 1967 G80CS is the 32nd from the very last one made and it was dispatched from Plumsteadon May 1, 1967, shipping docket K1614 and shipped to Joseph Berliner Corp. in New Jersey,then to Poke Cycle in Seattle, Washington when it was purchased by the original owner. Isubsequently purchased it from him. The very last G80CS manufactured was shipped to adealer in Canada during early August of 1967.Again, contrary to popular belief, there is no metal flake in theCandyApple color. The metallicappearance was generated through the use of a medium silver base coat which also was usedto accomplish the hand lining of the tank.What follows is the recipe for the base, color and top coats using PPG Deltron 2000 DBCAcrylic Urethane paint. I would suggest the use of PPG DPLF Epoxy Primer if there are minimalscratches on the bare metal surface. This can be sanded with two to three coats but generallynot much more than that. If the requirement to fill deep scratches and voids is necessary, thanfirst prime the bare metal surface with an appropriate PPG epoxy primer, then use PPG PRIMAK36 Acrylic Urethane Primer Surfacer. You can fill a large amount of scratches and voids toarrive at a perfect surface with this material.To mix ONE PINT of the base color, the formula is:354.4 grams of Deltron DMD690, with,106.6 grams of Deltron DMD689This gives a one pint total of 461.2 grams of Orion Silver (DBC34236).The silver base coat is considered to be a course silverPlace two coats of this silver on the tank as the base coat.To mix ONE PINT of the color coat (G80CSRED), the formula is:12.4 grams of Deltron DMX211 Orange, with,17.7 grams of Deltron DMX214, with,399.8 grams of Deltron DBC500This gives a gives a one pint total of 429.9 grams of G80CSRED(my name not theirs).Place 4 to 5 LIGHT coats of this color coat over the base coat of coarse silver.The final TOP COAT is Deltron DCU2042 Low VOC Speed Clear, but that can be substitutedbe some other clear coats. I would advise caution when substituting the Clear Coat to insurethat it is compatible with the PPG Deltron 2000 color coat.You can obtain a spec sheet on all of these individual parts and pieces by simply going to anylocal PPG dealer and asking for the following informational specification sheets:PPG P-196 covering DPLF Epoxy Primer,PPG P-169P covering PRIMA Acrylic Urethane Primer Surfacer K36 (it is vitally important toremember that this can not be used on bare metal,PPG P-175 Deltron 2000 Base coat DBC/DBI, and finally,PPG P216 DCU 2042 Low VOC Speed Clear DCU2042.The easiest way to obtain the silver striping is simply to mask the desired strips prior to applyingthe color top coat. The dimensions for the striping are available in the material that I sent to youand it has the correct spacing, widths, and parameters for the two stripes.http://archives.jampot.dk/Technical/Tan ... _codes.pdf
