Never seen this discussed on here before so here goes. How resistant is the Honda factory paint applied in the  60's/70's to fuel with ethanol in it?

I am sure Menno will probably be able to answer this.

The e 5 or e10 added nowadays to fuel is nothing more than cheap alcohol.
That doesn't affect paint much.

However; everyone always needs to be very careful with their original paint. Ever.

Does that mean that if I paint my S90 tank with cellulose paint Menno then  I don't need to clear-coat with 2-pack petrol resistant lacquer? RS BikePaints still sell the red  paint for that model in cellulose.

I would say; test it on a piece of metal first.
Paint it and see the next day how easy it is to wipe it off with a cloth with a bit of thinner on it.
If your cloth turns red I would suggest a clear 2k to seal the tank.

But surely the thinners is the solvent for the cellulose Menno. Isn't a fairer test to wipe it with a cloth with a bit of E10 fuel on it the next day?

I would prefer not to clear coat my 1960's Honda bikes because it looks too 'blingy' . They never looked like that from the factory.
