I’m wondering about paint removal…
Posted by Bobstamp on Saturday, January 16, 2021 10:34 PM

I don’t have the steadiest of hands when it comes to painting minuscule details on my models, so mistakes seem inevitable. I’ve had some success removing acrylic paint with Mr. Hobby’s Mr. Paint Remover, but less success removing enamel and Tamiya spray paint. (I use brushes, Tamiya acrylics, some lacquers, and spray paint, and Humbrel enamel.)

Question: Pledge Floor Gloss is often recommended as a final coat, but can it be used as an undercoat? I’m thinking that since ammonia can remove floor wax, is it possible to paint coat styrene with Pledge, paint over the Pledge, and then, if a painting mistake is made, to remove the paint and the floor wax with ammonia?

I could do a test, but I assume that you guys are bored and have nothing more to do than answer my questions!  Wink

Isopropyl alcohol at a concentration of 91% or higher will remove all of it.  For removing paint from an entire piece or assembly, a soak in the alcohol combined with scrubbing with a cheap electric toothbrush will strip it down to the bare plastic.  Its important to use an electric toothbrush because it scrubs in tiny strokes so it won't break little details off your model like a regular toothbrush would with its large strokes.  For spot removal (like if you want to gently remove the paint from a small area for gluing, etc.) dip a q-tip in the alcohol, dab the excess out on a paper towel, and gently rub that spot until the paint is gone.

I used to use Future as a barrier between paint layers, so that is something that is perfectly fine to do.  Alcohol (isopropyl only...not denatured) will remove all of it, no matter how long the paint/future has been on there, and won't damage the plastic like some of the stronger concentrations of ammonia will.  Ammonia is the reason for brittle plastic when people use things like Easy Off to remove paint.  No need to expose yourself or your model to things like that.

You can save on how many times you have to buy more alcohol by filtering the dirty alcohol through a coffee filter.  It will come out the other side completely clean and ready to use on your next stripping project.
