Those repro tanks look good, and are very reasonably priced. I need another tank for my K2 Bitsa to paint up so I can hang up the original (faded) paint K0 tank as “garage art”.
I think Yamiya source theirs from the original manufacturer in Japan that supplied them to Honda so I might buy one of theirs as shipping from Japan to Oz is way cheaper than from Britain.
As far as clearcoat goes, there’s clearcoat and there’s clearcoat. A rattle can of acrylic lacquer clear won’t last long, but a layer of 2 pack (not the rapper) clear will last for years, I polished then coated a pair of fork lowers for my K1 12 years ago, and they’re still like new now. Also, you could get it clear powdercoated, which will also last the life of the bike.
Then of course there’s controlled rusting. Leave it bare, spray a mix of vinegar, salt and hydrogen peroxide on your bare tank, this will make it rust before your eyes. Once happy with the rusty glory you’ve created, hit it with a good quality clearcoat as previously mentioned, to seal the rust in, and to stop it getting all over your pants every time you go for a ride. I’m not a fan, but it’s big in the rat bike/rat rod scene.
