Simple green has a low alkalinity of 9. For example water is rated at 7. Simple green is not the culprit, if it was, all my wheels would be peeling. Even Alufelgen has admitted that if it was something I did it would show up on all four wheels. Powder coating is a very durable finish and if the part has been properly prepared it would stand up to a basic biodegradable degreaser.
