No, I do not coat the coils and I suggest if the coils are not coated leave them as they are and the reason for this as a home owner if you apply too much then you run the risk of blocking air flow to the coil. There are some equpment out there that have a coating on the condenser coils but that is applied by the company at the factory, most air cooled chillers that I have work on have coated condenser coils and the coating is green in color.
If at all possible try not to use any chemical.....But if you do and the aluminum starts to turn black and starts to smoke you better start flushing with water ASAP.
