Just curious, what are people using nowdays to prime PE to stop flaking and scratching?? I have been using self etching auto primer and it works ok, but whats the best primer in the model paint world?? as I am sure you also have experienced, getting finish to stay on your parts can be a challenge.. thanks P.S, I have used old model master enamel from my stash as a pre coat, that works ok, but as you know, thats very expensive when you can find it nowdays..
