Yesterday I wanted to paint the first layer over my PST ISU tracks. The paint was not sticking to it nicely (undiluted Tamiya XF-1) so I washed the tracks in soap, hot water. And after that operation the tracks hate the paint even more! It's like painting the glass with water - paint just form in drops I tried to add some dishwasher liquid but it didn't help much. The only thing that helped was to wait for the paint to dry somewhat and then paint with thick paint.
Is there anything I can do to help the tracks accept their fate and become painted?
