Colorless Primer

I am unable to find online colorless primer for metals.

I want to rustproof steel railing but I don't want to change the color of it.

Does such a product exist? Can some one place a couple of links for that?

Primer does not suffice as a top coat so you'd need to paint it anyway.

No such thing as colorless metal primer, and you would top coat anyway so it doesn't really matter!

Rustoleum rusty metal primer is decent stuff for metal!

Would an automotive clear coat work for you?

If you put clear coat over a non compatible material, it;s going to check, plus a gallon of good clear can cost from $100 to $200 per gallon!

After re-reading, I wonder if OP is trying to put a clear coating to protect, vs a repair!

I am not planning to paint it afterwards. Maybe just 2 coats of Primer if there is a transparent one.

I don't know if the automotive one will work. But it sounds very expensive for 100-200$ per Gallon. Please send more information on that one...

My uncle who used to live in Belgium (Europe) told me that they had it there before. But he might be mistaking it for something else.

Is automotive clear not compatible with clean steel? I've seen dozens of old vehicles where they scotchbrighted the old finish and shot clear over the existing finish along with bare or rusty areas.

The only transparent primer I can think of is Gardz but it's a latex primer sealer formulated for interior walls. If you used something like spar poly it would yellow/amber what it's applied over.

There is not a transparent primer. Even if there was, primer is not intended to be a top coat so you need to paint this anyway.

Since it does not exist for all applications.

It is time for someone to work on this and create it...

The closest that we have is chrome which is a long and expensive process and it is too shinny for some requirements.

No, primer sticks to metal, paint sticks to primer, clear coat sticks to paint.

You have not really responded if this is a repair or a precaution, so nobody can really give you a definitive answer!
