This was the first time it happened to me, and I am sure I did something wrong indeed. Only, I'm not sure what I did wrong...pascalemod wrote:Did you forget to degrease the parts or you think the paint peeled because resin was seeping from under the paint? I have used the tamiya masking tape, and even stronger all weather blue tape and have rarely had paint lifting like it did (basically only once, on my Washington build). So Im very surprised you suffered from this, considering your experience. Id guess just a coat was thin on primer and resin was a bit greasy, or just a finger print got in the way. Either way, this has to be pretty rare event to worry about it.
Certainly it has nothing to do with resin, as I only had a couple of minor flakes on the resin hull of Victory but large flakes on the hull of the all-styrene Redoutable.
I did wash all parts carefully before priming. I'm never worried about mold-release agents on plastic kits, but I do know my fingers leave plenty of grease on my models during construction.
The amount of time I left tape on the models does seem to be a factor: the largest flakes occurred where I had left the tape for 4 or 5 days. But even when leaving tape on for several days, it shouldn't be a problem, so certainly I did do something wrong.
Flaking didn't occur between primer and base-coat, but between unpainted surface and primer.
So I Guess I did something wrong when priming? Maybe I built up primer coats too thinly, and the successive thin coats dried too quick and didn't bond strongly enough with the surface below? I don't know...
I would love to know what the problem was, so I can avoid it next time.
