Removing putty
Posted by smeagol the vile on Saturday, July 24, 2010 8:32 PM

I opened a kit I had started a year or so ago to find that I stoped because I had put on to much putty and covered some detail that I did NOT want removed.

 

how can I remove this putty without sanding it and the detail off?

What putty did you use? Testors, Squadron?

Dip a q-tip in laquer thinner, and gently rub the area where you want putty removed.  You may have to let a bit of thinner soften the putty up for a minute or two if it has ben dry a while.  Work slowly, and remember, less is more with the thinner.  You don't want it dripping, or sitting on exposed plastic around the area if you can avoid it.

Acetone (nail polish remover) is effective on uncured putty. Try a bit as it won't soften the plastic quite as fast as thinner. Worst case scenario sand flat and get the rivet gun out!

Ill try the laquer thinner.  I tried that with mineral spirits and it did not make a dent

Be careful as lacquer thinner will melt away the plastic as well as the putty.  Probably just be easier to sand away the putty and replace the rivets that are removed with it.

Yeah, if you SUBMERGE or drench the plastic!  Again, use a q-tip moistened in thinner, and run the putty.

Try alcohol first... If it cannot remove putty then use thinner. Becos , alcohol is not corrosive to plastic which means you can try to use as much alcohol as you want when you attempt the removal.

Cured Squadron putty is unresponsive to alcohol. It is likely that the only solvents which will soften the putty (eg. lacquer thinners, liquid cement)  will also soften the plastic. A more expensive option (which I've not tried), you may try something like Gunze or Tamiya lacquer thinners which are formulated to be less aggressive to styrene.
