Duplicolor automotive primer and tamiya spray paint

I'm having problems with this combination as the paint always seems to dry half-matte. I've given the spoiler for my MR2 three coats of paint but it never dries shiny. The surface looks porous.

It's a scratchbuilt GT wing made of evergreen sheets and given two coats of duplicolor primer. Any diagnoses?

How smooth is the surface you were painting on? Puttied up styrene sheet sounds pretty rough to me, make sure you sand it smooth, preferably up to 1500 or 2000 grit.

It sounds the same as my first car with duplicolor. It looks like an orange peel layer.. Probably you read the instructions and followed them.. That's were the problem sits, because at a spray distance of 25 cm // 10 inches the paint is already drying and comes partial dry on the car. So you have to spray at a shorter distance, like 10 cm // 4 inches but you have to go much faster to reduce the chance of runners. This is what I learned at IPMS last week from HRmodeler's second man Rinus.. hope that this helps

daggerlee: the surface was pretty smooth. i primed and sanded it

wishmaster: so i spray the primer from much closer up?

Yes and try to get some Duplicolor paint.. works better with eachother, Two different brands of paint//primer don't like to get mixed.. and why using expensive tamiya spray paint when you already use cheaper//better duplicolor primer..? Then use duplicolor also as paint.. enough choice and don't forget that some need clear finish.. so get that one also from Duplicolor.. works fine here.
