Dupli-Color Engine Enamel & Aluminum

[aacoop]

I have an aluminum master cylinder that is cleaned and sanded (180 grit)
Can i spray the dupli color black engine enamel paint directly over top of bare aluminum without primer
or
do i need an etching primer?

This item will not see any heat .. should i bake after its dry?

thanks

Just make sure the aluminum is clean from any sanding dust and oils. I usually give it a spray of brake cleaner, let it flash off then you can use the engine paint with out primer.

For heat curing.. do u let the paint dry 24 hrs then bake or do u bake while the paint is wet.. ?

Which product will withstand brake fluid better?

Also for the epoxy does it have to sit 7 days for full cure??

A: The paint should be dry before heat curing. 24 hours is enough time.

A: Cured Engine Enamel will. Keep in mind that brake fluid is very hard on paint so if the fluid sits on it for a long period of time there is a chance it will lift the paint.

Also for the epoxy does it have to sit 7 days for full cure??

A: 7 days is about how long it takes for Enamels to fully dry.
