Power-supply painting question

[ArtnShit]

Hi All,

Just cracked open my newly arrived Kaiju kit. Finished the Beepre2, so the timing was pretty perfect.

I am going to paint the bell cover of the PT-9 with Rustoleum, as I did the PT-9 of the BeePre2. While unpacking I was looking at the PC-5's, and it got me wondering if there was a way to remove the side bell covers, so I could give them a paint job. Is that possible? Additionally, the metal band going across the pc-5 is covered in a waxy and sticky residue. If I take that off with some acetone, will that be detrimental in any way?

Thanks!

You definitely don't want to try to take those apart.  You can certainly sand on the metal covers and just paint over them, but if you take them off you could disturb the air gap in the choke and they would have to be replaced.

You can paint the choke covers by carefully masking off what you do not what painted.
Carefully clean/sand the covers prior to applying any paint or clear coat.

Amazing! Thanks for the advice, I will try this today.

As for the gunk on the top center band of the pc-5, would it be ok if I lightly cleaned that with acetone, or would I need to cover it in something else afterward? Attached is a pic for reference.

The residue on the channel frame can be removed. The frame appears to be steel, which will rust quite readily unless coated with something, so you'll want to apply paint or some other coating. Depending on conditions, that can start pretty quickly once the metal is bared, so take that into account in planning your project.

As for what takes that residue off, I've usually sanded them. However, the residue has usually seemed to me to be something like dried varnish, as opposed to something waxy. If you use a solvent, definitely use it sparingly and be sure none gets inside the choke.

I used acetone on a rag to clean those parts.

Just gently sand the channel frame till it's mostly smooth.

Thank you for all of the advice! I am lightly sanding the banded area then going to paint that, leaving the bell covers clean. They have a much cleaner finish, so might as well not mess with it.
