I have heard that some pinstriping was done by the 'dealers' not always by the factory, but I think it only related to 'specials'?. I would assume that BMW put pinstriping on the outside for economic/production reasons. It is easier to paint/clear coat on a production line in one process rather than interupt to have the striping done by hand and then put tank back on the line. Remember we are going back to before modern digital dye vinyl stickers and the factory process probably used something like silk screening - better endurance? than new stickers but a lot more expensive. Current digital dye stickers dont have very good UV resistance and particulary red dye fade quickly - so modern stickers are under a clear layer to get UV protection. Back in the oldddd days of course the whole process was by hand and they could include paint additives (such as lead - good UV resistance) therefore the striping could have been under the clear or not.... but in the end does it really matter, one advantage if the paint is still good it is easy enough to replace the striping if it is on the outside (but make sure you use 'solid' (all they way through not just dye on top) coloured vinyl so it fades slower.).

Actually it wasn't that long ago. BMW did all their pinstriping by hand at least up until the late 70s and maybe even the early 80s.

I suppose it all depends, I met my first girlfriend in the '70s......that feels like a loooong time ago.

All the green /5s I ever saw-and I uncrated new ones-were non-metallic. I don't know whether they were clear-coated, but I find it hard to believe that they were. The pinstripe is the final part of the process.

The green bikes were not easy to sell.

Sure do love the late model look and shine but to me it doesn't seem to fit right on a 40 year old bike.
I am looking into this at the moment and have been thinking exactly the same. Modern two-pack paints, clear over base, just don't look like anything from the 70s. Wayyyy higher gloss levels. Modern paint is glorious but doesn't look period-authentic to me.

We need someone with an original BMW paint job to test by rubbing with solvent - alcohol, and then again with some acetone. If neither will shift it then its a match for modern paints. Anyone want to do this for me on their pride and joy? Anyone?

I doubt anyone ever offered any metallic paint schemes that weren't clear coated. You would get a very uneven look when the paint wore. Also, metallic coats are sprayed thin to make them pop, they're translucent so they would need protection, including UV.

As suggested earlier, call Holt BMW in Athens, Ohio. He does professional painting and uses Glasurite paint. He is factory certified to paint new replacement parts for BMW. His name is Kent Holt and will sell you the proper paint.

Oh, I don't doubt that they used clear over base in the 70s, at least on the metallics. My question is whether it was solvent (single pack) or catalysed (two pack) paint. Modern two pack paints have a depth and gloss that looks un-naturally excellent on old bikes.

When i had my 1973 repainted the body shop matched the paint under the side panels.
Audi Cricket Green Metallic matched.
They were surprised the original paint was base/clear.
