1970 914-6 Bottom Paint Question? Options

[racerbvd]

I got a big question on our 914-6, on the bottom, mine has been painted a different color (from the factory) and undercoated:confused:
My paint guy says that he finds no traces of Blue on the bottom and that the color & under coating appear to have been applied from the factory..

This is a Concours Restoration, so it has to be correct, so on one hand I'm thinking just Paint the bottom the matching Blue, but on the other hand, Porsche was also known to sometimes spray the bottoms with what ever was left in the Spray gun and I know of one collector who has a few 914-6s, like mine, both 70s and both OEM, yet one of his 1970s Six's has no coating; another '70 does:confused:
I need to figure this out ASAP as the car is ready for Paint..

I think because it being metallic 2 stage in 1970 they didn't spray the chassis 100% like they did in later years, Like Andy say there is usaully the grey and then body color and then the black light pebble black undercoat, The dealer sprayed undercoat is heavy and globby.
All the non metalic -6's I have delt with are sprayed 99% over the beige, and then have the black pebbly undercoat on top. Later cars are painted 100% color and then undercoated and some not. Just my observations

Your floor pan black pebble undercoat is like the many -6's I have owned.

Thanks, this makes the most sense, and we have found out that this is and has been the number 1 controversy at Porsche Concours, for the past 25 years, since Porsche & VOA had an agreement NOT to undercoat, & Porsche didn't offer it until 1972, yet, there are still cars like mine, that clearly were coated BEFORE they got to the ports (some dealers in the US had arrangements to have the cars coated upon reaching the ports, different vendors, some really good, some not. We researched this, talking to one of the top Porsche restorers, and the #1 guy according to PCA, but with NO factory documentation, and most of the Porsche people who were involved at that level either have retired or passed on:( it doesn't look like it will ever be resolved..
So looks like we will go with a shiny, bottom...
