  • Powder Coating

    I'm new to the world of Powder Coating, but I believe it's going to come in very handy soon. I've got my ovens set up, (both small and large). I put them in Dee's garage and when she came home, she was a bit skeptical. I believe her parting words were...." you'd better not burn the house down"!

    Question for the group...what parts did you powder coat during your restoration? Second question, If you have the dual voltage gun, which parts did you use high vs. low voltage on?

    Third question...has anyone ever made their own silicone plugs to block the holes & threaded holes that shouldn't get coated? Seems like a pretty straightforward process and I've been watching lots of videos but have yet to do my first part.

    Here is the gun I purchased from Eastwood. https://www.eastwood.com/dual-voltag...SABEgJQXPD_BwE

    Cheers,

    Good decision, Kevin.

    For your questions, I powder coat just about anything that will fit in my oven. My oven is bigger than your small one, but smaller than your big one.

    I don't have the dual voltage gun, but I'm looking at it.

    I bought an assortment of silicone plugs, but don't use them much now. I find it's usually just as easy to chase out threaded holes if necessary. I do use a high temp green tape to mask, though.

    Right now, I'm building an exhaust hood to do the spraying in. Without it, the powder over-spray gets on everything. It's not like paint over-spray--it doesn't stick, and brushes off easily, but it is still a bit of a pain.

    Be sure to report back on your first batch.

    For just a little more, you can do it yourself!

      Yeah, you need to try something before the Mitty so you can tell me about it. I have the ovens already.

        For me, if it fit in my 30 inch oven, it got powered coated. I also have a powder coat business close by that I used to powder coat the frame, wheels, front cross member and other large items. I have both the single voltage and the dual voltage guns. If using the dual voltage gun, I use the high voltage for any parts that do not have any joining surfaces that have less than 5 degrees. if the angle are tight, I switch to the lower voltage which usually allows the powder to coat the interior surfaces. At the high voltage, the surfaces in the tight angle does not get covered do to the high electrostatic forces created in the tight angle joint.

          Keven, good plan.
          As Ed says ,Do everything .Why Not?
          When I lived in the Seattle area there were coaters about on every corner.
          Here in Chucktown very sparse.
          In fact I have an oil pan that needs to get re done as the person who did it first did the inside and the flange.
          Well, the inside is starting to flake and rust.
          I will have it blasted and ceramic coated instead
          is there any ceramic DIY kits available.
          Yo might want to try that too

                We have powdercoaters pretty much everywhere and they are competitive. For the cost, I always had them clean, strip and coat the parts. It was reasonable enough to not warrant me an oven setup in the garage. Aside from that, most of my parts were much larger that would not fit in a standard house oven.

                  Kevin - I decided against getting my PC own set-up, though I'd like to have had it - due to space issues.

                  But I've had several parts done, starting with a valve cover in crackle-black and the front-cross member (which I later re-did in gloss black. It was a bear to remove the silver, so make sure you choose the color you want!!).

                  Both turned out well, and are very durable.

                  I'm actually interested in getting into plating ( inspired by ed_h).
