Liquid Power

09/25/2007 10:22 AM

I am sorry if this has been discussed already, but i am looking for something(liquid) that can easily penetrates old layers of paint, the paint that you can find on old cars, for instance. The idea is to leave the liquid there and then dust the paint away , effortless. Anyone? Please, this is an emergency......

Guest,

I don't know about "dusting" the paint away, but you can "peel" it away.

Check out Dumond chemical company (http://www.dumondchemicals.com/).

The manufacture a line of products called "Peel-Away", that are used to remove paint from various substrates. The products are sprayed or painted on the surface to be stripped, and then covered with a fibrous barrier sheet, and allowed time to soften the paint (several hours or overnight). The fibrous sheet is then peeled away, along with most of the paint. Residual paint can be easily scraped off, as it is softened by the stripper.

The stripped surfaces must then be properly neutralized, depending upon which Peel Away product is used.

This stuff isn't inexpensive, but it does seem to "do the job".

The active ingredient of this is methylene chloride, a.k.a. dichloromethane, which will seriously disrupt most plastics and biological materials on contact. It is a clear gelatinous fluid.

Claims to contain no methylene chloride, though has a statement regarding its unsuitability in the presence of plastics. Comes similarly branded in a bottle as a clear gelatinous fluid.

Both the above can be found at a range of home improvement retail outlets.

There is another product called 'Modelstrip', which is used by model makers and which contains an amine as a plastic-safe active ingredient in an off-white paste that needs to be prevented from drying out in order to work (an illustration is not available for pretty obvious reasons.....). It is better suited to small areas of application.

The usual disclaimer applies (the only contact with the vending company is as a satisfied customer).

FOLLOW THE SAFETY INSTRUCTIONS ACCOMPANYING THESE MATERIALS!!!

Perhaps less costly and easier to find, try dimethyl acetamide. It has great dissolving power, plus it has a low evaporation rate. "Paint" on car bodies is much more difficult to dissolve or strip than "house paint".

while it is true DMSO is not particularly toxic, it does have a tendency to solvate materials and carry them through the dermal layers into underlying tissues and blood. This is why track athletes dissolve painkillers in DMSO and apply it to their legs. So anything dissolved in DMSO can end up in your bllod stream, and may not play fiendly there. Though anything organic that disrupts plastic paints is usually a strong organic solvent and should be used with care (Methylene Chloride is particularly bad to play with and will dissolve even heavy rubber or nitrile gloves).

DMSO is not toxic, and it is true that DMSO is an excellent carrier but the particulates must be microscopic. If someone is to remove paint from a car they should use gloves.

Chemicals used by the industry to remove paint are toxic, DMSO is not toxic and can do an excellent job at low cost. Any comparison of toxicity of DMSO to industry chemicals is not even a fair comparison. Water is toxic in excess. Care should be used with any product.

And it is great for your arthritis too. It is sold to horse trainers for use on sprains.

Be very careful handling DMSO (dimethyl sulfoxide). By itself it is not toxic. But it easily passes through human skin, taking along with it any *dissolved impurities*. People have used it to soothe arthritic pain, but it needs to be very pure. It can probably passes through many plastics too, so choose your protective equipment carefully.

While we're on the subject, does anyone know how to remove fibered aluminum roofing compound?

I've tried paint stripper with no success. Mineral spirits seems to soften it better than the stripper. I have contacted the manufacturer and they say to not remove it. I would like to remove it for weight and appearance reasons.
