Mjolnir / General Paint Durability Help!

[ChiCubsGordon24]

Hey Fellow Makers!

I'm hoping I can get some suggestions on painting techniques. I'm having an issue on my Mjolnir prop where the paint is rubbing off fairly quickly from use as seen in the attached pics. I 3D printed everything in PLA plastic and SLA resin. I have a layer of primer then paint then clearcoat. Curious about other techniques that can be used to make a more durable finish that will withstand handling and use. Any help or links to other threads would be great.

Thanks!

I would suggest a thicker clearcoat layer and better prep inbetween layers. Clearcoat shouldn't come off so easily unless scratched. Rubbing off is unheard of to me. What brand are you using?

I typically use automotive-grade acrylics, since they seem to be more forgiving then enamels at least IMO.

Well specifically in the handle rings its a resin print followed by a coat of rustoleum primer. Then 2-3 light coats of Alclad II paint then the Alclad Aqua Gloss sealer. I'm assuming maybe the resin print was too smooth?

What about cerakote? It's a durable gun coating application. Last I recal they had two versions, one you can bake on, and one that was air-dry. I think the bake one was only like 10-15 mins and you can bake pla in the oven to harden it.

Thanks, I'll look into that.

I find Alclad wears off pretty easily. I tend to use Testors metallizer sealer over them which seems to be a bit more durable.

Were the resin parts washed thoroughly with alcohol and soap and water after that to get rid of any and all residue from the printing process before priming?
