mr2_dude11-12-2010, 06:00 PMI am interest in doing some work painting small part of cars on powder coating like intake manifold,valve cover,etc. the bigger part I would paint is a wheel. so I make some research and I found a the powder coating gun and some few color powder like matte,metallic (very nice), hi-temp, etc.

my question is if anyone have work with powder coating with a similar gun kit? and how look the finishing product (results)?
do you have any pictures of a product worked with some kind of this Powder Coating Kit?

Colors:

Prep work is key to a good outcome anytime you paint or powder. If you think you have sanded long enough, then sand more. Use a really good primer coat and be sure the imperfections are out. Powder is a little more forgiving than paint but blemishes will show if a crappy prep is done. Do you have a way to bake it? mr2_dude11-13-2010, 07:20 PMI used a powder gun from Harbor Freight and got a lot of compliments on the parts I coated on my bike.

I need to get a house oven for the cooking, I read that it need to be a electrical oven, why is that? why not the gas oven? FC88MR211-13-2010, 08:33 PMI need to get a house oven for the cooking, I read that it need to be a electrical oven, why is that? why not the gas oven?

I have no idea about the oven thing. I used an old gas convection oven to bake my parts. They turned out fine. Unless they are worried that the gas may chemical react with the powder some how. I have never heard that but im no pro powder coater. mr2_dude11-14-2010, 12:09 PMI have no idea about the oven thing. I used an old gas convection oven to bake my parts. They turned out fine.

at the first post you say that you "Use a really good primer coat" you mean that before throw powder to the part need to spray primer and then the powder?

and what powder do you use the cheap one on Harbor freight or the hotcoat from eastwood?

do you have any picture of the parts that you powder coat? FC88MR211-14-2010, 12:59 PMat the first post you say that you "Use a really good primer coat" you mean that before throw powder to the part need to spray primer and then the powder?

I used the powder I bought from a body shop called Overspray Customs in Troy, TX. I can't remember what the name of the powder I bought, but it was around $60 for the color and primer. The primer is powder coat also, but was a littler more fine and filled in more smooth than the color powder. I baked after I primed and baked again after I powdered with color. I prepped my parts which included my lowers on my front shocks, risers, forward controls, and handlebar controls. I had to remove all the rubber and plastic seals, sand the protective coating Honda puts on their aluminum, and for S&Gs I sanded the lettering off of all the parts. I then used a degreaser and brake cleaner to be sure their was not oil or other chemicals on the parts. Then I rinsed with Dawn soap and water to be sure the cleaners was off the metal. I lost all of my photos and the write up when my computer crashed back in Sept. I will check and see if the write up is on the forum I posted it on. The bike is history as I crashed back in July, totaling it.

This was my first attempt at powder coating and I'm not sure I even did it the correct way with the primer and baking. I baked my parts at 450 degrees for an hour and then applied the clear coat powder. and baked for another hour. But the parts I did turned out well. I am not sure of longevity of the way I did it, because I crashed about two months after I did it all. Sorry I can't help more. mr2_dude11-14-2010, 01:14 PMI used the powder I bought from a body shop called Overspray Customs in Troy, TX.
