You lucked out in that you applied the stuff in cold weather. Easy-Off has a goodly portion of lye in it(NaOH), which EATS aluminum and magnesium. Guess what your transaxle and engine cases are? You're lucky you didn't end up with some large corroded spots. In any case you'd better paint things, you've probably taken off any anodizing/surface treatment that existed. I used to work in an anodizing plant, they used a solution of NaOH for removing badly anodized coatings from parts for another go-around, took about 5 mins. at 90 degrees. Untreated magnesium surfaces tend to disappear into a pile of gray powder, pretty fast if you have some salt around(like on the roads) This Easy-Off stuff might work well with American large car parts which tend to be ferrous, I'd still use a pressure washer with some detergent instead. Commercial firms can Alodine-coat aluminum and magnesium parts, this is a proprietary gold-colored, chemically-applied coating, dipped or sprayed on. This might be what the original coating was. It's usually used under further paint or lacquer coatings to help with adhesion.
