I've been using Dawn dish soap to clean my parts. Give them a good rise in clean water and like Doc said ,do not touch with bare hands. Has worked well for me, and less expensive than acetone.

You'd have to make absolutely sure your parts are dry if you do use dawn and water. You don't need to submerse your parts in acetone just a wipe down will work. Moisture and water are enemies of powder coat make sure you don't get moisture into your powder it will ruin it.

Running a day or two behind...what else is new :lolb:. Anyway got the masking done today, a tedious task. Maybe tomorrow I can get some powder on some of the parts at least and cure them. Added a couple of pics below. You can see a few sacrificial screws and silicon plugs in the cylinder especially. Just noticed....the flywheel bore will be plugged as well before coating.

First attempt done and I am  pleased for the most part. Only had a few minor places that didn't get sufficient coated but for the most part will be hidden by the cylinder lagging, etc. I will be a bit more generous the next time with the powder. Another thing that will help is a more spacious coating booth. Will give that some thought. I was surprised that clean up was quite easy though this would be better done outside weather permitting.

Anyway a few photos.
1. Parts hanging from the oven rack.
2. Parts after coating.
3 Parts in the oven.
4. After cooling and with the masking removed.

Now to reassemble and get it running again.

Hello Bill,

Looks real good. You may have already stated, but what color is that..black? Or a blend? Thanks for sharing this process and please keep us up to date.

Have a great day,
Thomas

Thomas it is called " mocha metallic". One of the available colors from Eastwood. I think it will look good once reassembled. Thanks for looking in.

Those look great, Bill!  Doesn't look too horrendously hard.
The color looks very nice too!

Thanks guys, it really wasn't and harder than their videos show and it is easy to tell when the powder begins to flow out. As with anything like this the masking off is a bit tedious but no more so than for regular painting.  I am hoping this will be a good durable finish. Will add another picture or two once I have reassembled the engine.

Hello Bill

Powder coating appears to be a tough durable finish and doable in the home shop.

 I understand how you need to bake it on, to melt the powder onto the surface.

What is not so clear to me, is how you apply the powder to the metal in the first place. Do you need some sort of spray gun adapted for powder and do you need electrostatics to attract the powder to the metal? Maybe I missed that part of the explanation somewhere in a previous post

Mike, take a look here and especially at the video down towards the bottom of the page. https://www.eastwood.com/hotcoat-powder-coating/powder-coat-guns.html

But to answer your question, yes it is a specialized gun where the parts are grounded and the powder is charged. Surprisingly though it takes very little air pressure 5-10 psi and volume so a small compressor works just fine. I think the video will show the process completely.

Thats a great kit setup, including the oven. Did you get the original or the dual-voltage version of the gun? And the tape they have for masking can stay in place during the baking process?

Chris, I got the dual voltage just in case. Gives you another option at least for not that much more. Yes the tape did stay in place. I did make one mistake and that was to wipe the parts down one last time after the tape was in place. It worked but next time I will complete the cleaning first and use gloves while installing the masking tape.
