I've painted a few metal miniatures but not many plastic ones and I'm painting up a space marines Rhino to light it as a demo model.

I did a bit of research about priming and painting etc and primed the pieces with Plastikote white primer which is what I had in the cupboard. Some of the pieces have gone a bit sticky which is the first problem.
The second is that when I tried painting over the primer with Citadel paint as a test to see if the primer was ok when it's dry the black paint is scraping off - photo attached.

Any ideas what I've done wrong and do I need to strip back and start again? If so, does thinners take it off?

Any help appreciated.

How thick is the primer coat that is being applied?

A.

Not that thick. I did a couple of light coats and it looked a bit speckly in places and thicker nits looked slightly wrinkled.

Redfinder looks to be a far more experienced painter judging by his banner so take his advice if offered, but my two cents is that I have had better success with spray primers rather than brush applied and I just use a cheap generic spray.

I have found Plastikote primer to take several days to dry completely.

People, more often than not apply too much primer. I would recommend getting a quality primer. Most automotive primers are ok, Vallejo makes a good one for airburshes but my favorite is the p3 White and p3 Black primer, best out of the can I have ever used. The following two articles I wrote should be helpful. When primer is applied to thick, paint can not properly adhere to the model. The purpose of primer is not to cover the whole surface, it is to prepare the surface for paint.

QFT. Listen to this man, his advice has helped me take bounding leaps forward in my painting.

Thanks all. I've bought some Halfords acrylic primer today and cleaned off the old stuff as best I can.

Thanks for the links. Had a read through of those and some useful tips.

I'll have a test go on some of the sprues and hopefully get it right this time!
