Short Note

It makes for an interesting look,perhaps for a one off just to show off the amount of AM someone might have used,if have never done this,but in general,I'd rather see a finished off model.

While the subject is open, what are y'all using to prime your PE?

I forgot what I've used in the past, but I recently tried using Stynylrez which claims to work for styrene, resin, and metal but it didn't adhere very well.

For priming PE, I'm using Gunze Mr. Metal Primer.  Its a transparent etching primer, so I follow that with some Tamiya Grey Primer just to make sure everything looks right before the paint goes on.  It works great.  The times I have had to remove a little bit of paint from a PE piece that was primed with that, it actually took a little bit of effort to remove...rather than just falling off like it normally would.

You definitely want to use it in a well-ventilated area and limit the amount of time you have the bottle open.  The fumes aren't obnoxious fumes that spread through the whole room or anything, but they're a stronger version of what comes off of CA...really makes your eyes burn if you keep the bottle open for too long and are sitting right next to it.

I like the idea of using a dedicated metal primer, and because of Gunze' reputation and longivity, I have to assume it truly is formulated for metal. I also like the word "etching" in your comment.

I just had a chip come off my current project's PE disk brakes while pushing one of the axle assemblies into place, which is why I asked.

Thank you!
