whats the best way to apply decals, I saw that guy on youtube who use first mark softer then he airbrush a mixture of Tamiya clear and flat base.

Jamal, the agreed on best way is to put down a layer of clear gloss then the decal, use setting solution (I use micro set/sol )to get it to conform to any surface detail. After the decal has settled down and dried cover with a flat clear of your choice to protect it from further weathering.
good luck!

Jamal,

There are several methods, but like Stoney I start by spraying a layer of clear gloss (Microscale's Micro-gloss) and let it dry. Then I apply the decals, brushing each area with a puddle of Micro-set just before the decal goes on, then blot dry with kitchen towel once in position. (If it moves while blotting, just add more water with a brush and nudge it back into place...) Once blotted I add a gentle dab of Micro-sol and leave it to wrinkle & snug down. If there is any silvering (from trapped air under the decal) puncture it with a knife-tip and add more Micro-sol. (Excessive silvering is a sign that you probably needed more gloss to start with - flat paints have rough surfaces that trap little air pockets under decals, leading to poor decal adhesion.)

It can take several applications over the course of a day or two to fully settle a decal over uneven surfaces. After the decal is fully snugged and dried (a day or two later) I spray a layer of gloss to seal the decal and hide any edges. After that I hit it with clear flat (I like Pollyscale's Flat Finish) and carry on with weathering.

Other techniques can be equally effective, but this is what I do. Hope it helps!
