176 forum posts	Hi, Can anyone recommend a decent Dukem pen on eBay UK for me? I have a tin of engineers blue which I can mix up with meths, but having a pen would save time and hassle. Thanks 😊

Alcohol or acetone works as a solvent. A pen for it would be a struggle because it'll tend to dry out on the felt tip and need re-wetting to get it to work again. A paint brush sealed into the lid of a bottle or jar, and kept submerged during storage works very well, as does a sheet of paper shop/kitchen towel rolled up tightly and dipped into the bottle (re-wet or use another next time).
