This website came from a reliable source, another bike forum. They say this stuff has great adhesion: http://www.brownells.com/gunsmith-tools-supplies/metal-prep-coloring/paint-finishes/air-cure-aerosol-paints/aluma-hyde-ii-prod1117.aspx

I used VHT Engine Enamel "Universal Aluminum" and I am very pleased with the results. It matched the paint inside the chain area (which I did not repaint) almost exactly. A little bit brighter but that could be because the original paint is 38 years old. Two coats of VHT primer and then three coats of paint.

In fact in this pic you can compare the new paint to the original paint behind the points plate.

Hey Red - that does look great.  What did you do as far as prep?

I had taken apart everything except the crankcase.

• I used Aircraft Stripper to lift the paint
• On the top end parts I then used my puny soda blaster, as shown in my restoration thread, to clean off the residue
• On the crankcase I used a micro fiber shop towel to wipe off the residue. Some areas needed a 2nd application of AS
• In places where the old paint was missing and the aluminum was oxidized and rough I used 1000 grit to smoothen it up
• Prior to painting I used a paint brush with copious amounts of acetone in the nooks and crannies. Larger areas were wiped down with acetone and a towel
• I followed the painting instructions, with 15 minutes between each coat of primer and paint
• All the top end pieces were then baked in the oven for one hour at 200F

The smell from the oven isn't too bad at all if you use your kitchen exhaust fan. Smells much less than a freshly painted room. Those of you with a tolerant spousal unit shouldn't have a problem

The only way to do it I have found is to have the cases stove enamelled , this does not stain or flake when petrol oil etc is spilt on it. Also it's a thin coating so all detail, engine numbers etc perfectly clear.

Be careful with the paper towels you use with your acetone as any chemicals or colors in the towels can potentially leave residue causing problems.
