Walter.. thanks for joining us. When you say "fade", it might mean that is chalking over, or sometimes it's called antiquing. You should try to add some protectant to it and brighten it right up. We recommend the new 303 Aerospace now. We sell it here
http://www.axtell.com/catresor.html You might be able to find it locally also on the web somewhere.
Our latex puppets have a special pigmented latex as paint but they are coated with the protectant. The protectant acts as a barrier and needs to be removed before repainting. We don't recommend you doing it, but here is what we do. We use a solvent to remove the old protectant and the affected paint area down to the latex substrate. Then when dry we repaint it with the pigmented latex paint and replace the protectant. Paint color matching is also important so it does not look like a patch. We recommend that you send the puppet back here for a reasonable cost touch up but understand that the cost of shipping back and forth may be high from Holland. If the area is just black and in a place where the area is solid you can touch up with a black permanent felt marker. Experiment in an unseen area for rub off. Ax
