I'm on some heavy duty muscle relaxers...and my spelling lately has been interesting to say the least...

I can't believe that I spelled that all correctly...LOL [img]<<GRAEMLIN_URL>>/hmmm.gif[/img] [img]<<GRAEMLIN_URL>>/beers.gif[/img]

Looks great Jason!

That's pretty good results from a backyard chemistry set. I've been getting like results from my basement lab using nothing more exotic ( read cheap ) than lye and vinegar. Only using them on cast iron or steel though, and not mixing the two chemicals together.

What does that Purple stuff do to aluminum?

[SuperNovaSS]

Not sure what is does to aluminum. I know lye with take out aluminum. I have used it to get aluminum out of heat cross overs in steel heads before. I will have to put a piece of scrap aluminum in there to find out.

My son recommended Purple Power a few months back. He uses it in his parts washer. I bought a jug but haven't used it yet. Never considered using it for paint removal. [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

Years ago we used Westley's Bleche-Wite® to remove paint from plastic model cars. Just let it soak overnight and scrub it with a soft toothbrush. Worked wonders.

Just tried Purple Power out on an Aluminum Thermostat Housing for a sb/bb Chevy.

I won't do that again. [img]<<GRAEMLIN_URL>>/thumbsdown.gif[/img]

I only had it in for about an hour. Full strength Purple Power took off some more of the left over paint and goo, but the bowl was foaming and the aluminum was changing color. The housing came out pretty dark. Luckily I didn't leave it in overnight like I had originally planned. I had a speedo reducer housing (zink?) and gears that I had left in for two days and the P.P. loosened all the old grease and crud. Worked fine on that. Gonna try some plastic parts next. I think I'm gonna like it though. Just don't put any vauluable parts in there with out trying it on a junk part first.

Good to know. Thanks for the heads up. I have left oven cleaner on intakes too long before and had the same result. A quick bead blasting returned the original aluminum sheen.

I would not let anything other than plastic soak in the stuff for any length of time, full strength. I will errode aluminum and discolor steel (and remove skin).
