Hello,

I'm currently needing to paint some brackets that are inside and outside of the wings, and I'm thinking either 2k acrylic or I was wondering whether to even try some brake caliper lacquer (I believe it's epoxy-based), as this'll be hard-wearing and more chip resistant.

What I don't want to do is paint them in something that'll hide any nasties such as fatigue cracking going on behind, hence powder-coating is out, if I understand correctly.

What would other people's opinions be?

Thanks in advance.

I see that you are overwhelmed with replies.....

Well, maybe you are really asking about how much to spend on paint!

When I recovered the fuselage on my fabric Piper I used Randolph two part epoxy paints on both the steel structure and aluminium cowlings etc.
Take a look at https://www.lasaero.com/products/article/N01RNMP3P
These are high quality "aviation" primers and paints, but the downside is cost. Also, they only come in quart kits (or larger).

Rattle cans of zinc chromate primer are much cheaper but, as the Randolph information states, aren't as good.
I suppose it depends on where your fittings are located and if they can be removed in the future for repainting, if required.
Personally, I would go for the best primer/paint that you can afford....

Powder coating is often used on steel engine bearers and seems to provide a good, corrosion-proof, coating, but can get chipped.
Hope this helps..
