you will find that the epoxy paint is much more durable. Looks exactly like the original color will not need rubbing out and with a coat of wax looks outstanding. It dries slowly and sets up really hard.

waiting for Sandy to come visit. Rain and wind right now. Expecting 60 mph winds lots of rain tonight. Some rumors it will stall out on top of us. Hope anyone else in the VA. MD. DC NJ and Deleware area stays safe.

155 parts prep new [Re: JonH]

Got these parts back from bead blasting today. I only had the very base of the mount done and the counterweights, as I am trying to preserve as much of the original as possible.

Didn't the manufacturer (N.S.) fill all the imperfections before they painted. I've seen stripped parts that had a black material in the holes. JB weld would work. Except for powder coating ??? Right ???

I painted my 128 counter wieght with Rust Oleum textured. It is a fine textured finish that i think looked very much like the original finish on the counter wieght. You would have to fill the casting flaws though first.

I'm wondering if this is more a sign of the years the weight spent in the garage having rust eat away at it. I'm not sure with the amount of filler I would need to use and smooth out, I will end up with a better result.

Found this at Advance Auto. It is a high build formula sandable "filler" primer. It worked good for filling pits (fairly deep) in the tube of my RV-6. I guess it just depends on how "slick" you want it and how much sanding you care to do.

Primed the weights today. The guy at the garage strongly recommended priming as soon as possible. After only 1 day I could see "flash" rust already lightly forming on the bare metal. Lightly sanded, then steel wool, washed in soapy water, rinsed and then paper towel dried followed by my wife's hair drier before I primed. Was also advised to brush
paint the primer to better penetrate and get in nooks and crannies. Will then lightly steel wool and do another coat of primer tomorrow night. After studying original pictures, and advice from a friend, decided to use wrinkle coat spray paint for final coats. This appears to be the closest to how these were originally. Here is the "before" shot again...

Not brass, don't see weights inside (just baffles).

Not easy to take a pic of the finished counterweights and get the right lighting/flash/glare combo, but here is a before and after picture.
