Dry eraser board or coating 1

[FeldmanWill]

Mechanical engineer here. I need some sort of inexpensive sheet manufacturer or coating for dry erase purpose. Perfection is not an issue but cost is, it's not for classroom just some once in a while labeling labeling.

Thanks in advance
William

I'm looking for something more direct, I can not go over $.10 per 6"x12" surface.

Well, what's wrong with just painting it with enamel paint?

There are tons of solutions for painting kids rooms and classrooms. I'm looking to hit $.1 per 1/2ft^2 for coating or same price for a same size sheet of dry erase board or coated metal/plastic, this stuff to be mildly petroleum product resistible, machine washable.

I don't know what's wrong with enamel paint, first stop Home Depot after work and I'll post what's wrong/right with it.

Try a little can on a sample board and see if it is satisfactory... then buy a gallon or two...

Enamel worked like a charm and almost meets cost requirements out of Home Depot. Now the thing is to figure out enamel orepoxy paint, which one is more durable, but that's small potatoes.

Thanks for all the help.

Any tips for making enamel stick to aluminum. It's fingernail scrapeable which is not desired. I bought aluminum primer and scoffed up aluminum piece prior and still enamel and epoxy can be scratched off. Is there a painting technique or product that can solve this problem?

Bill,
Proper pretreatment for aluminum painting takes place in at least a 5 stage pretreatment system. The system would consist of the following stages:
1: Alkaline cleaner (aluminum-safe, or mild etch)
2: Fresh Water rinse
3: Iron Phosphate solution containing fluoride
4: Fresh Water Rinse (Recirc DI Optional)
5: Fresh Water Rinse (Virgin DI optional)
Choice of cleaner depends on alloy and soils to be removed. Do some research or ask in the shop. The fluoride is the key. It etches the aluminum surface to provide for good paint adhesion. If you reduce the stages, then you reduce the chances for success.
Cheers,

Yep thats kind off what the proper way spells out.

Aluminum is picky. And nobody made one product can.
