Re: How do I get a nice finnish on my prop...
Looks like it's maybe just hard water deposits and some rust to me. If so, you can shine that thing up real fast and easy. Go spend $2 at a local home improvement store and make yourself a 50/50 mix of muriatic acid & water in a bucket. Wear rubber gloves & eye protection in case you splash, and it'll just wipe off with a sponge while you get an occasional whiff of nasty stuff up your nose. Have a hose handy and rinse everything with plenty of clean water when you're done.<br /><br />It'll work beautifully, will get every bit of gack & rust outta every nook and cranny, and will take about 10 minutes to make it look like brand new without scratching a thing. I've done this on many props over the years.<br /><br />However, it will do nothing to remove cosmetic scratches, if that really is your biggest problem. Stainless is tough stuff to polish to a high shine and will take a LOT of elbow grease. Try a high speed rotary tool with some metal polish on a buffing wheel and see how that works. You can't hurt it. If it were me, I'd forget the scratches and just leave it as-is after a good cleaning.<br /><br />Important safety note, always dump the acid in the water, NEVER dump the water in the acid.
