Don Terrill’s Speed-Talk

I need to remove some weight from some sheet metal. What type of acid should I use. Obviously I need to be able to use this in a kiddy pool or some sort of tub. I don't figure the paint stripping type places use an acid that is strong enough. I have used Muriatic acid on some experimental pieces but it takes a long time for very minimal material removal. If I am doing this in the back yard I need to also be able to dispose of this sort of legally.

as far as i know, i does take time.If you try something stronger you loose control

I would definitely suggest this as NOT being the way to remove weight from metal.

Its dangerous, its nasty, it can screw you up for life if something goes wrong.

Using small amounts ie filling a port or an intake manifold runner, sure, that can be dealt with, but dumping it in a big open tub of acid is a good way to start a very bad day.

Imagine the little dumb kid wandering off into your yard and coming across it, or the dog getting a good whiff of it and suffocating to death in your yard. Good times explaining that sort of thing, esp. if its your kid or your dog.

Kind of a question on the same topic. Were would I be able to find a directory of companies that will acid dip a whole chassis?

Thanks in advance,
David

Let me save you a whole heepa truble boy, take yer parts to a profeshunal. they use a much stroger hydro cloride than you can buy and thers no mess, as well they have a variety of diffrent sollushuns that they use before and after to deal with the rest of the crap on yer parts like paint grees, seem seeler, bondo and all the crap in a chassy, they also use a reel nice conditioner after so all yer left with is a cleen part or car, and it smells reel nise too! if you want to know who duz it in yer area contact a local manufacture that does production line painting they use thees fellas on a regular basis for cleening the fictures and jigs the parts go down the line on.

like my one legged uncle bumpy always says!
Play safe!
