tom,
great boat choice. i agree that the light blue looks different in most photos i've seen. however the crimmin photos show same light blue on the '64 - '67 boats in similar lighting conditions.
i think ownwer shirley mcdonald would have insisted on identical same light blue paint on all boats, '62 - '68 including the '65 SHU SHU.
the newton 103 -M 1965 ND paint sheet i have does not show paint code numbers. paint descriptions are "blue sides and cowlings, dark blue striping on engine cowling and
medium blue U-7's.
based on my crimmin photos i think that rustoleum spray can light blue is very close. i suggest getting the graphics from mike gossler at PGI or other reliable supplier and then match the U-7's. the rustoleum light blue matched the U-5's and the blue in the Notre Dame college crest for my '65 SHU SHU which had the same 1962 ND light blue sides and cowling. i'm reasonably certain that the '64 - '66 ND boats had exact same light blue as the '62 ND and the '65 SHU.
the '65 SHU was the rebuilt / repainted '62 ND. my point is that all of the ND's, 1962 - 1968, had same light blue and white paint schemes. ( the '65 SHU having the mahogany deck ) the crimmin photos of the '65 SHU parked next to the '64-'65 ND show identical light blue in my opinion.
the newton 1965 SHU SHU drawing 106-B shows paint codes as follows : dupont blue 43500 and white 7372 ( i don't have the '62 ND paint sheet 106-A )
good luck,
dave
