Spray paint issues

[hotrod59f100]

I had 2 cars I was spraying up and came upon 2 issues. The first car was a Nsx I was going to paint yellow ,I used velspar white primer and after the proper dry time I spayed the yellow gloss. When dry the Paint on the roof hat a textured finish like rhino liner for Turks beds and the sides as smooth and glossy as can be. The other. was a rx7 I planed to paint green. I used automotive dark gray primer then when dried I layed out the green which is also valspar. As it shot out of the can I could see thae texture was the same as the Nsx but no gloss any where. Some one told me it could be that the cans have to low of pressure? Does that sound right?

Shane,

A couple of questions here:

1. How old is the paint? I suspect that over time a can could lose some pressure.

2. Was the paint subjected to extreme temperatures? A thorough shaking of the can is necessary and if it was stored in a garage over the winter, you may need to "warm" up the can by putting it in warm water to get the paint flowing properly.

3. Did you do a test spray on a scrap body before hand? Whenever I am using paint for the first time I always do a test spray, just to make sure it flows correctly and the tip isn't clogged. A tip a car painter friend taught me years ago!

Hopefully you can figure out what the problem is/was and move on. Frustrating to have paint problems!

i'm big for the lacquers from Testors/Model Master and Tamiya, hard to go wrong with those paints. do they cost more than the "big" can from Walmart? sure they do, but the end result is worth it.

Agreed.

1st paint was brand new.

2. My spray booth is 70 at most times.

3. No I wish I had.

i know a lot of people will disagree with me here on this but i'd recommend sticking with hobby specific paints if you are going to spray bomb your models.

why do i say that? because they are made specifically for spraying model kits and styrene plastic. i know that the big cans of Krlyon, etc. are "cheaper" than the hobby paints, but are they? it's certainly not cheaper when the paint fails for whatever reason and you are stuck with stripping the model or dealing with one that's been ruined.

I am normally. I had great success with the testors but it was a color tey dont have

the other thing i'll recommend is sticking with a "system" and by that i mean if you are going to use say, the Testors/Model Master lacquers, use the whole system from primer to color to clear. same with Tamiya's lacquer line. by doing that you know that the primer, paint and clear are all going to work together and not have any weird compatability issues.

Ont the Nsx I did vesper primer and gloss yellow.
