    Wish me luck...before and after blasting pics. Powder coating likely this coming weekend.

    After looking closer the shock tower braces are actually from my 76 Mav, not the 72 Comet shown as "before"....they all looked about the same but the maverick appears to have some extra holes in there.... you get the idea though!

    Aha I see what you did there. :)

    Anyone have any recommendations on what color to powder coat all my brackets and hinges and what not? I was thinking black but I want to add a nice little pop to the way it all looks. Eventually I plan on having a 302 under the hood and the engine bay will be red like the rest of the car. I'm not sure what color scheme will look the best.

    Before you Powder coat be sure you "Gas off" the parts (place in oven until the parts are 400 degrees F for 6-8 min).

    This will eliminate any off gassing causing pot marks. Here is what I did with an Eastwood Powder oven and an un- branded SEARS Powder coating gun, like this one on ebay. They can be found for $49-$59 free shipping there. They have bad reviews since the locking button breaks off and slight dusting around seal. So, I just use masking tape to tape on the powder cup. I added extra ground to my work by running wire from grounding rod to the rack adding a natural ground. Works for me.

    You will notice that they are not perfect, I was in a rush.. I did not gas off the parts first. I will live with them. If I choose to re-do them I will need aircraft paint stripper and soak overnight to get the coating off.

    Most things in life aren't perfect but you did a damn good job.

    I bought an Eastwood dual voltage hot powder gun gen 2 which is a bit pricier than many other models but had great reviews. We will see if it's worth the $109 shelled out for it this coming weekend. I like your black more than I thought I would....I'm kind of like a crow, shiny things get me.

    I ordered 2 lbs of the hotcoat powder mirror black with a high gloss clear to go over it with. I think it will give me what I want or at least close. I will get some pictures up after I have coated some.

    Had to buy a new sand blasting gun already, the cheapo one that came with my blast cabinet already failed. Hoping everything arrives by Friday/Saturday. Amazon stuff will but I have no experience with Eastwood directly until this order....I'm gonna guess that stuff won't be here until next Tuesday because I didn't order soon enough. This will of course delay any follow up pictures

    I did not clear, just gloss black. If you are going to clear you will "Hot coat" the parts. After you bake for 1/2 to 3/4 time that your powder recommends pull your parts out, give a minute or so and shoot the clear. No need to ground parts since the heat will hold onto the powder and assist in fusing the clear to the base. Return to oven and bake for recommended time for your clear powder.

    Do you have Handheld Infrared Thermometer that will go up to 500 degrees F? You will need this as when baking, the time starts when the parts reach the recommended temp. My powders needed reach 400 degrees F and then hold for 15 min.

    I don't have one of those at the moment. Do you think local retail will have this in stick - home depot, Menard's, Lowe's....or do you think I better find one online quickly? From your experience what price is sufficient to get the job done?

    If you plan to use home Oven plan to buy a NEW one for your wife..... DO NOT USE GAS OVEN!!!!!

    Go to Goodwill get small toaster oven to practice with on smaller parts then find an old elect oven for garage...

    Way ahead of you there. When I decided this was something I was going to pursue (buying blast cabinet, powdercoating equip, etc) I found a cheap older electric oven on craigslist for $40. No issues that I can see so far although I have only heated it up to 350 a couple times to make sure it works. While I didnt use a thermometer, it appears to get the job done.

    Thanks for the links on the infrared gun - identical product but on sale at lowes for $10 off- great timing!

    I ordered the tape with some of the other supplies - 72 ft should get me by for awhile...where do I find silicon plugs for threaded pieces? Those shock tower mounts have threaded bits on top...I hadnt even though of that...you definately saved me a headache there.

    I wish I had done a bit more research before committing to media. I bought glass beads to start that were quite expensive. It was slow going on thick rust so I switched over to coal slag which I got twice as much for 1/4 of the price. The coal slag leaves a rougher finish so I might strip with it and switch over to glass to smooth out the final surface before hitting it with powder.

    Good idea or waste of time? Thoughts?

    You are on the right track. Coal slag cuts rust like a hot knife through butter. I would try powder coating some test pieces before spending any more $$$ on glass bead. Glass is great for cleaning aluminum manifolds, heads and the like, but I would never use it to cut rust. You can also try aluminum oxide and play with your nozzle pressures to find the best finish for paint or powder. That rough finish will hold on to paint like a magnet,but take care not to touch it with your bare hands after blasting as it will rust very quickly. Use Nitrile gloves from Harbor Freight to handle your parts after blasting. They are cheap and effective.

    Powder coat is good, but you also might want to experiment with POR 15. It is very hard and leaves a VERY glossy finish. It will require a POR topcoat if exposed to a lot of UV light but otherwise, it works great.
