I use it a lot and can highly recommend it. Just make sure you keep acetone and lock-tite away from it even when cured. As mentioned, it takes about a week to fully cure but you can speed up the process by puting in a 90 degree hot-box for two days. I have never seen it mentioned in any Aluma-Hyde II instructions about baking, but if it works...
You must follow the directions completely and allow at least 24 hours before even touching it, more if it is humid. Once cured it is very durable but as with any paint, even the epoxy Aluma-Hyde, it can scratch and chip. Howver, it is very easy to touch up. Sand with 400 gritt or 0000 steel wool to blend the chip/scratch and re-coat, and wait another week. It works on almost anything, plastic, stainless, aluminum, steel, and holds up to heat pretty well on flash suppressors, and there is no need for a primer.
