How should paint feel to the touch? Primers, Base Coats.

Hiya 

I'm new here and to modeling in general, and like many before me and after me i need help understanding the painting process, I have the Aoshima G-West Lancer Evolution kit and i started spraying today everything seems like it went off without a hitch however I was surprised to find the primer quite rough, and the base coat has a egg shell/satin finish, is this normal?  Should these coats feel smooth to the touch? almost as smooth as the plastic itself? I also made the stupid mistake of using too much turpentine to remove errors i made in hand painting the window rubbers,some paint and primer, i believe, were removed during the process, will i have to re prime the blemish before adding more coats of base paint?

Setup

Spraying outdoors "no booth"

Tamiya  TS-13 base and light grey plastic primer. 

Thanks in advance

Regards

A little "tooth" in primer is okay, but too much will mean extra work getting a good shine on your final finish.

I like sanding primer with #800 Wetordry, used wet. This will give a surface about like a sheet of typing paper, if that makes sense.

Hard to say, what do you consider rough?  Tamiya primer has some texture but if there is too much, it might be drying too much before it hits.  If you are using rattle cans, you might need to get a little closer.  If you are using an airbrush, you might need to add a touch more thinner or get a little closer.  Like Snake said, I usually use 800 wet to prep the primer for top coat.  Looks smooth, but flat (ie, not glossy).

It feels slightly rougher than typing paper.

I used Tamiya grey primer, rattle can, it was very hot yesterday so i decided to scuff the model up and prime later in the evening, tried posting photos but it seems to be a struggle...

 

Thanks for the replies !

Heat and humidity will affect the paint.  Too much heat and it will dry too fast, and may be too dry when it hits the model resulting in a rough appearance.  Humidity is also a killer especially in the evening.  The paint cools as the solvent flashes off and if the dew point is close to the air temp, you can get moisture condensing on the painted surface which will pretty much ruin the paint job.

Overall, it sounds like you are close if the finish is a little rougher than a sheet of paper.

Painting usually takes some practice to get right.  I painted an entire full-sized Dodge M37 truck with rattle cans in semi-gloss.  Took a lot of thought and a few more coats than necessary to get the right look.
