Worthwhile painting a new gas tank?

[challenger7070]

The new gas tank is a Spectra with Ni Terne coating (lead-tin) and has an oily/waxy coating.
I'm wonder if it's worth paint the outside of the tank with a 2k epoxy.

Supposedly Ni-Terne has very good corrosion resistance and reading forums, many install as is. But then I thought... if the corrosion resistance is so good, why is there a waxyoil coating on it. This is an extra cost to the manufacturing process and is something that's typically done on bare sheet steel to prevent flash rusting in storage and transport. Even replacement sheet metal panels for our cars are simply electro plated black with no coating on them.

So I'm wonder why if NiTerne is good at corrosion resistance (better than electro plating), would they be coated in this waxyoil substance?

Not sure whether to epoxy it or not.

I wanted to add some protection but wanted to keep a somewhat OE finish.. I ended up clear coating with a light coat of 2K.. That was years ago and it still looks exactly the same...

Nice that still looks brand new! Was that simply scotchbrite scuff and paint? I have 2k clear laying around that would work.

I was thinking if I use 2k epoxy primer, it needs 80 grit prep, and perhaps that might remove or noticeably reduce the lead-tin coating, so might not be adding much protection, more shifting the corrosion protection from one factor to another. Not sure which is more durable of the two, so not sure if it's worth undoing/reducing the effectiveness of an already potentially stable coating if going with 2k primer epoxy.

So in a way scuffing for 2k clear would barely reduce the current niterne but help add a bit of protection.

I cleaned it so the oil coating was removed and to be honest I don't think I risked scuffing it..I didn't want to alter or scratch the coating..
