I have found that I get much better adhesion on plastic parts by cleaning with Simple Green to remove any release agent from molds. It's amazing what Simple Green will clean!

Al, steel: I use aceton.

For the metal parts I get teh cheap lacquer thinner from Walmart... whatever that stuff is in the blue and orange can. For plastic, soap and water.

Home Depot for acetone to degrease the metal parts/ cleaning up the airbrush, and a gallon of denatured alcohol for degreasing the plastic parts.

Simple green will work to degrease, but must be flushed, and then the parts take too long to dry.

I have good luck using brake cleaner for degreasing. Seems to work very well. That or sometimes I use M.E.K. Only use that if you have a respirator!

M.E.K. is Methyl Ethyl Ketone, which is a powerful solvent used in some glues and paint thinners. It is nasty stuff.

I just blow them dry right away with air hose after rinsing in water.

Go with Simple Green and a toothbrush. This will remove most of the grease and dirt. Keep washing it until the water sheets off the metal after rinsing. If it beads up at all, clean it again. Wear rubber/latex gloves so that your fingerprints don't add more grease to the metal. Make sure you spray simple green on the gloves, wash and rinse them well to remove any material that may be on the gloves from the manufacturing process.

An additional step to remove any grease that you can't get at is to use acetone or MEK, but if the part doesn't have any hard to reach areas, you can skip this as long as you thoroughly degrease it with the simple green.

One other thing that you may want to do is after your first pass of clean-up, heat the parts up to about 100'F for about 15 minutes. This will draw out oil and grease from areas you thought were clean. Then go back over it again with Simple Green or carb cleaner.

What the differences between carb cleaner and brake cleaner?

And when you're done, give it to your wife to clean her nail-polish off.

I use brake cleaner.

MEK is also the thinning agent used in Norrell's MolyResin. So if you are using that, you should us a repirator rated for organic compounds. It is also one helluva degreaser!

Don't be afraid to use brake cleaner. I use it even though I have MEK handy. Brake cleaner doesn't leave any residue. I have been doing it this way for all my refinish jobs using MolyResin and have never encountered a problem. YMMV

CRC makes a spray cleaner for electrical components that cleans well, evaporates quickly and leaves no residue.

I think it called electa-motive or something similar.

Same company that makes the original Brake Kleen.

I have always used acetone.

I use the simple green engine degreaser. Works great and a gallon (7 bucks) goes a long way.

I too have used simple green. Just dont let the residue stay and dont let the water you use to wash it off stay too long either.

I just did a molycoat upper. It is in danger of looking like a professional job.
