Painting heat exchangers

If you do go the cleaning route be careful with pressure washing, the fins will be beat to hell. Purple power is awesome and works very well but don't let it sit on the aluminum long because it will etch the aluminum and leave it looking hazed. If you want to soak it in cleaner use something like simple green.

Well, after all the input, I decided not to paint it. I did hit it with some degreaser in conjunction with a power washer, focusing mostly on the end tanks to avoid potentially damaging the fins. It looks better, but will need some detail work with degreaser and a brush.
