I just duracoated my AR and there is some lettering I was trying to paint different colors. I used testors model paint and tried tried wiping off the paint the bled over with acetone. I noticed that the duracoat was coming off a little and dulling the finish. I tried the paintfill after about 36 hours from when I put the duracoat on. Is there any chemical that is safe to use that will wipe the model paint and not damage the duracoat? or is there a certain curing time when the duracoat will not be vulnerable to the acetone? any info would be greatly appreciated, Thanks.
