Winfield Judson 27 rolling chassis

[B.C.]

We start by sanding the frame and grinding the rough spots.

After we slick the parts that are seen we epoxy prime it and then apply the paint.

Just a hint. Follow mixing instructions % is important when it comes to mixing paint and getting it to dry correct.

Hi B.C. What exactly are you using, type, and brand? Is it available in a good range of colors?

The base is a DP90 epoxy primer by PPG with a DP401 catalyst the 401 is for etching metal. I'm using concept on the frame but only because it's black any other color I would probably use DBU base. We are a PPG shop I would recomend that you stick with one brand from a paint store that is helpfull to you.

[B.C.]

We use feather fill for the first prime

[B.C.]

You can never block to much.

[B.C.]

We just sand the interior as it gets covered.

[B.C.]

Block once then prime again.

Thanks for the info, B.C.. I'm a DuPont kinda guy here, but am familiar with PPG paints. Still kinda leaning towards powder coat on frame, but paint for the calipers, and shock, and rear end.
Bet it is tuff to get good finish,(wrong description) ah,, no over spray when doing inside and outside body parts. Been thinking of spraying inside of delivery first, then masking it off before spraying outside. Still a couple months away from that.
Please keep your build post going.

Time for a lot more blocking

[3quarter32]

Oh boy, the fun part. Can hardly wait to start on mine,,,,,,,NOT! At least the weather if cooling off a bit for this. Body is looking pretty good from here.

I have to ask do you use sealer before or after prime?

Kinda tuff question. A lot depends on the primers being used. Some are primer/sealers. I have never used a sealer except when I have had some unknown paints that have been previously put on, and didn't want to go all the way to metal or bare fiberglass because of custom body work under the paint. Then I use a water base sealer. You can then prime right over any types of paints that have been used.
If you plan on driving the car after primer, then I would seal the primer. Water will penetrate primer. It will cause rust to form under the primer if a metal surface us under the primer. Fiberglass body of course will not rust, but oils, fuels, and other road matter can soak down into the primer.
For me, I will not use a sealer, since I will not prime until I get ready to actually prepare to paint. I have done a small pit of pit and scratch filling, and covered with rattle can primer. It will be removed when paint process really starts.

Kind of hard to answer, as many variables are involved. If you are planning on driving the car in primer for a while, it should be sealed to keep contaminates such as road oils, and fuels. bird dropping, etc. from soaking into the primer. Even oils from your hands can be left in primer. Water will also penetrate primer and cause rust issues if over metal. Epoxy primers need not be sealed, but are the pits to sand before color is applied.
I use a primer/sealer right from the start, but never drive in primer before the final finish is applied. I have done a bit of pit and scratch filling, and covered with rattle can primer. This will be removed before actual primer process begins.

Thanks that will help me a lot when I get ready to get my project. This bit of information will help since I have read most everyone likes to drive their cars before painting to take care of little problems that show up during a test drive.
