camarobuilder Posted December 13, 2010 Share Posted December 13, 2010 This is the sleeper from my "Movin On" Kenworth. As you can see, the primer is showing through around the door and the roof. I'm using Tamiya fine white primer and Tamiya Racing green. Both out of the can. I'm warming the cans in hot water and shaking the heck out of them. I start with a few mist coats, and let them tack up between them. I'm also painting in 70 degrees. I've got a second sleeper that I'm going to try painting. Would it make sense to spray a flat green after the primer, before the gloss color? Any thoughts or tips would be greatly appreciated. Thanks, Frank Quote Link to comment Share on other sites More sharing options...
Lownslow Posted December 13, 2010 Share Posted December 13, 2010 dark color over light never works out youre also spraying too heavy if you mist a few coats yu have no problem Quote Link to comment Share on other sites More sharing options...
Brendan Posted December 13, 2010 Share Posted December 13, 2010 The other problem you might be having is the panel lines are too sharp of an edge which is making the white show through. If you take some sandpaper and just go along the edges of all the panel lines, you'll soften the corners up just enough so that the paint won't pull away from the edges.

spkgibson Posted December 13, 2010 Share Posted December 13, 2010 For dark Colors I use gray for Blues and Greens,And Red Oxide for reds and earth tones like dark browns and everything in between, I would have gone with the gray, Now the Tamiya white works great for painting light colors like yellows, Tans and pale blues and greens also,I have found out that most of the time you can use the tamiya paints over bare plastic. I do it all the time,And have had only one issue where the kit was molded in the AMT Gray, And I tested a yellow they make,Well it wouldn't cover it after 5 mist coats,But that green you used I painted a 47 Crosley the same color and used Duplicolor sandable primer first, And had no issues. Just remmember white for you Light solid colors, Gray for you Metallics and darker colors, And the Red Oxide for your really dark colors and browns and blacks and other various dark colors. I hope this helps . Quote Link to comment Share on other sites More sharing options...
Agent G Posted December 13, 2010 Share Posted December 13, 2010 Ditto all the above. My take is the sharp panel lines combined with the white primer is the cause. G Quote Link to comment Share on other sites More sharing options...
samdiego Posted December 23, 2010 Share Posted December 23, 2010 (edited) But you have to think about the why. The problem is putting paint on heavy enough that it gets together with itself and it flows away from the edge. The coats of paint need to be so thin that you think it will never cover. You need a lot of coats timed after flashing so the paint can't move. You might be able to hide a lot of the problems with your cab using a Detailer type wash into the panel lines. I've had that work. Edited December 23, 2010 by samdiego Quote Link to comment Share on other sites More sharing options...
