Probably best to neutralize the acid with a base solution then wash and add protective coating. Any before, during and after pics?
I am helping a friend get a 1975 GoldWing back on the road after a very long slumber. One of the side jobs is making the bike a bit more presentable, removing the rust bloom from non painted parts. The GoldWing muffler is a huge one piece unit with bolt on flashes of chrome each side, underneath its black painted steel. After warming the bike up we mixed muriatic acid 1:1 with water and using a small trim paint brush soaked the hot muffler with the solution. In minutes the acid dissolved a very thick coating of rust. It is amazing to see how fast the acid combined with heat cleans the old muffler to shiny steel. Finish with header paint and looks great. Brushing the solution on the frame will not damage paint but is gets the rust off quick so that a brush on coat of Por-15 satin black can freshen the frame. Try and keep the acid off chrome for any length of time as it can discolour the chrome. Works great on rusty fasteners as well, just brush clear coat over the bolts and nuts once the acid has done its work. Make sure to do this outside in a well ventilated area and wear rubber gloves. Keep a hose near by to neutralize the acid .
Hey Canuck,I don't see a satin black paint on POR-15's web site. Is chassis black a satin finish? Thanks.
I remember looking into the muriatic acid/ hydrochloric acid idea for chrome and stainless steel pipes once or thrice. While the results of many a pipe Ive seen look absolutely magical, there were lots of folks needing caution or straight up advising against using the acid, as over time it eats into the metal regardless of how fast you think you got it off. It was enough to scare me away, but maybe one day Ill give it a go on these stainless aftermarket pipes.
Yes, 'Chassis Black' Direct to Metal Top Coat is what I usually use.
I would stay away from trying to clean chrome plating with acid, and acid will remove a zinc coating very quickly. I think the acid should be restricted to carbon steel oxide.
Have you tried using any of their engine paint in a brush on mode on a motorcycle engine?
For rust on chrome plating.. aluminum foil and water. Trust me on this one, it doesn't sound as if it would do anything.
