I've gotten everything off the rear of the frame. I'm ready to pull the front control arms and whatever is left up front. Once it's bare, I'm going to have it sand blasted.
The next question is coating. I've heard mixed reviews on powder coating. I've heard mixed reviews on Por-15. I've heard mixed reviews on the Eastwood Chassis Black Epoxy.
What's a guy to do? Powder Coating sounds like a long term/durable solution in a lot of ways. That said, would the coating be to thick to the point where it would cover the stamped VIN in the frame? I know no one can see it when the body's on the car. But still I'd like keep it viewable if necessary.
Has anyone had recent experience with just a black epoxy? What color am I going for in general? Semi-Gloss Black? Is the issue with durability the prep or just the nature of the epoxy?
At a certain point, I'll just pull the trigger on something. But I figured a light discussion about it couldn't hurt.
To be honest, whatever you want. Factory frames were semi-flat black lacquer, nothing fancy. You do not necessarily need powder coating, POR, or an epoxy. I would agree you do not want a product that could potentially fill the frame stamps.
Hi D,
I didn't realize frames were painted with lacquer.
For some reason I've thought that 68-69 frames received an asphalt based coating and 70-72+ frames were dipped in Dupont 640 enamel-based paint.
What are the mixed reviews you've heard about powder coating?
Regards,
Alan
I've heard that if powder coating is too thin that water can get in between it. I'm more concerned about it being too thick to where you can't see the stamped vin. Does powder coating retain grease pencil marks and what not?
Hi D,
If you're concerned about the stamp's legibility I'd take a picture with the frame stripped, one with it coated with whatever you decide to use, and lastly, one with the body in place.

Just use GM Chassis paint 100.00 a gallon on ebay
As factory as you get, spray it on your self
if the car is stored in a garage which I think you are going to do,
Give it a couple coats and be on your way
Unless you park and drive in the rain or winter driven then powder coat it
Don't know how correct you want but the sky is the limit

Had my frame blasted and powder coated and can read the frame stamp just fine. (I blacked out the end of the VIN... don't really want it online.... and hope you don't mind the dust! )

I did my own sand blasting and used POR semi gloss with couple coats one quart worked on last coat I added about 15% flattner in place of the POR thinner
Wes
Used semi gloss then flattner this was a ver rusty frame as you will see in next picture .Just put couple layors duct tape over vin stamp before sandblasting
Hi D,
People use various methods and products with varying results. It depends what you want the finished appearance to be and how much effort you want to put into the frame.
I was fortunate in that my frame was in good shape so I stripped it myself and had it powder coated.
I then sanded the entire frame and sprayed it with Krylon #1613 semi-flat black.
That gave the frame the appearance I was looking for.
Beware of having a pitted frame powder coated. People think that the coating will hide the pits and smooth the appearance. But it doesn't, in fact it exaggerates the pitted appearance.

I used POR15. That is some hard paint! A wire wheel is needed to remove a little where you want a good ground connection. Before you sand blast, protect the treads on all welded nuts by screwing in cheap bolts.
Hi D,
I really think that the media used and the pressure at which it shot affects the surface of the part being blasted.
I'd say if the 2 areas where the stamps are located were blasted long enough the stamps could be annihilated.
If you're concerned you could put a piece of duct tape on each stamp and ask that those 2 areas not be blasted. Afterwards you could clean those areas using a more gentle method.

Alan
