About spray painting a plastic model

I’ve painted some parts with Tamiya spray paint from a rattle can. When it dried, some spots were glossy, which I wanted, other spots were dull and flat. Why? Maybe the pigment and the material that causes the glossy finish are both in the can and maybe I just didn’t shake it enough to thoroughly mix them. Maybe there’s another issue? I have tried spraying clear gloss over plastic models before and it’s always unsatisfactory, so I’m hoping that there’s a way to get the finish I want with one can. Any ideas? Suggestions?

I’ve always had good luck with Tamiya, so I’m surprised to hear this. What paint was it? Was the plastic clean? Do you use primer?

Some Tamiya paint colors work better than others.

But they respond well to repair. Just wet sand the areas with 400 grit and repaint. Tamiya paints blend well - usually you don’t have to repaint the entire model.

Getting a perfect finish the first time is a miracle, no matter the brand.

You need to talk to Rocketeer. He’s an Artist!

First, as noted above, talk to Rocketeer if you can.

The material may not have been clean and possibly required sanding to keep the texture consistent.

Thank you all. “talk to Rocketeer” ??? With the old SDMB it was pretty easy to contact a member. Here, I don’t know. They don’t make it easy, it it’s their intent.

Ah, right. Try to talk to @Rocketeer.

I immediately pictured one of my models, where the problem was that I’d gotten a minuscule amount of oil on the plastic, from my (clean, I swear it!) fingers.

My solution? Suddenly, it was a fighter jet sporting desert camo!

Sounds like an area got tacky and then got hit with an overspray.

You think Rocketeer is the only good model builder here? Just because people like me don’t build what is considered “kewl” and post pics here?

My response is accurate and on-point. You want a lesson on how to paint, I can do that. Prep work is 90% of a good paint job, but NO ONE gets perfection the first time. There’s always dust, hair, fisheyes, runs, blemishing. Same as real cars. There’s always repairs.

?? What’s a fisheye?

The only kewl technique I ever learned was dry-brushing, to highlight things like rivets, and to give a “used” look to things like tanks. Road-splash, etc. I’m a dry-brushing evangelist!

Water in the paint. It looks like little circles in the finish.

Dry brishing is great! It really wakes up a model.

Thanks for the kind comments, but it sounds like you guys have this handled. As Just_Asking_Questions said, lightly sand the dull areas with some fine sandpaper, maybe 400 or 600 grit wet-or-dry paper. Keep your sandpaper wet, really wet, to help avoid scratches.

Then respray, starting with very light coats and slowly building up the color. If you don’t like the gloss, you could give it a coat of Tamiya Gloss Clear or (my favorite) Testors Wet Look Clear.
