Help: I have a close-up painting of iceplants that was scratched by movers. The paint was removed along a line down to the base gelcoat. The painting was finished with Golden's Polymer Varnish with UVLS. Do I have to remove the whole coating before beginning repairs to the painting, or just around the damaged area? What should I use to remove the polymer varnish? The bottle just says the finish may be removed with an "alkaline solution" but doesn't offer any suggestions for any particular removal formula other than suggesting ammonia and water. What mix should I use? Any suggestions would be appreciated. The paining prior to the damage is shown below...

You may want to call the folks at Golden and see their suggestion.

My first thought is a very mild solution of ammonia and water. Test with a q-tip/cotton swab dipped in the solution and gently rub the surface to see if the mixture is right. If it isn't strong enough add more ammonia, if to strong add more water.

You may only need to do an area slightly larger than the area to be repaired.

Be sure to revarnish after an isolation coat. Should blend right in.

Good luck.

I second idylbrush. Look at the website from Golden in case that they already have that question in their FAQ. Otherwise contact their support.

I just had to contact them this week and found them friendly, helpful and very quick to respond. And that was me contacting the European support from Germany where their paints are not very well known. I imagine that the US ought to be at least as good.
