Cleaning up paint runs...

Thanks for the tips!

I did manage to strip some of the runs with mineral turpentine (and one or two I did have to sand, they were too thick). Luckily, it was just the coat of primer, so I didn't have to be too careful, looks like it worked.

However, there is still the other problem - my botched-up final coat on another model, it has some runs in it. I'm going to try to carefully sand them away... Hopefully the decals underneath won't get damaged, if I use very fine-grit sanding sticks...

Any other tips on what to do without causing damage are still welcome!

 

 

 

 

I've used the technique Tim described and it works well.  The main thing is to make sure the paint has really cured rather than being simply dry to the touch.  Several years ago, my gloss coat on a Spitfire dried with a pebbly finish.  Rather than trying to strip everything, I just carefully wet sanded the the surface with #600 which smoothed the clear coat while preservng the camo underneath.

I don't know if this would help in your situation, but I recently had success in removing some hardened paint blobs caused by airbrushed paint that had run on the fuselage of an aircraft I was working on.  Using mini sanding sticks of very fine grit, I carefully sanded each blob down flat, but not so far as to go through the paint to the plastic.  I would stop frequently to brush out the paint particles from the stick.  When they were relatively  smooth and level, I polished the areas with a soft cloth.  Finally, I sprayed a coat of clear gloss overall as decals were to be applied.  It is nearly impossible to see where the blobs once were.  However, Yaris, it sounds like your runs are in clear coat already over top of decals, so this might not work.
