Alain, using the Microscale system, you should first apply Micro Set (Blue bottle) to the model surface where the decal will be placed. Slide the wet decal onto the model & after it's positioned properly you can wick off excess fluids with a paper towel & gently press the decal down from the center out to get rid of any trapped air. I usually let the decal set for about 1/2 hour & then apply Micro Sol (Red bottle) only to the decal surface. Do not touch the decal after applying the Sol!!! After an hour or so inspect the decal. You may see some sign of wrinkling but that's normal. If the decal is unwrinkled but not pulling down into recesses, you may have to re-apply Sol. Depending on the decal, it may take a few hours to fully set. You can repeat Sol application on a cured decal, although it will have less effect.
Jules, ModelMaster Gloss Dark Sea Blue is a near perfect match. Just remember that the Gloss enamels take considerably longer to cure than the flats & are best applied in several light sprays rather than heavy coats.
