The Stovebolt Site Forums The Shop Area Paint and Body Shop Orange Peeled Paint

Man am I Bummed..I removed my oil filter assembly from my 54 3100 235, degreased it, cleaned it with soap and water, steel-wooled it, wiped it down, primed it with a self-etching primer, let it dry and put on a nice first coat of engine paint. It turned out great but there were spots where I could still see primer so I waited until the next evening and recoated it using the same spray can that I used for the first coat. Right away I began to notice the first coat begin to orange peel and become very wrinkly. I don't understand. What could I have done wrong???

I would say you waited too long to recoat. Some paints must be recoated in a limited time frame.

Read the directions on the paint can. It should tell you the maximum recoat time.

When painting any engine part there is always oil, whether you think you got it all or not. If the oil was on there long enough, its been baked on, and probably "soaked" in the metal. When you cleaned it, there was probably a very thin film of oil that you couldnt see or feel, where it is now orange peeling. Make sure your paint is engine block enamel . I found a wire brush sander works well for getting the grime off, and follow up with some denatured alcohol, or thinner to really clean the grease and oil off.

Hope this helps

Bruce, that's not so bad. It's only a canister. Dinkin' around with small parts and pieces is the fun part of fixing up a truck, no matter how long it takes. Atleast that didn't happen while painting something bigger....like the whole truck!

There are some changes going on in the paint industry where solvents are being replaced with different solvents to meet VOC levels. The bad news is some of the VOC exempt solvents are very aggressive and will dive in and attack previous layers especially if they are only partially cured, like your 1 day film.

It would be interesting to hear how that paint manufacturer spelled out the re-coat window parameters.

Spray can epoxy paint will react the same way if you re-coat or spray a second coat on it. I have found that most epoxies can be applied in only one coat situations. The second coat will lift the first coat.

Another solvent which is good for removing all greases and oils from items to be painted is Brake Clean. I have concluded that if will clean brake parts and remove brake fluid and grease from them, it is pretty good stuff! I have used it succesfully and after using it, wipe the part down with denatured alcohol and proceed to painting.
