I went with Rand-O-Fill for the base and it works great. The polar grey will cover in one coat from my test. I will have the wings base coated tomorrow and Sunday can try the yellow and see. I found that if I lift the lid on my laser and crank up the blower and do the doping in front of it then no fumes are smelled anywhere in the house, and I checked airflow, I open the door to the garage and there is a breeze that flows down and into the room. I just need to set up a work bench in front of it now for applying the dope and I'm good. Everything has been Nitrate coated and sealed, sanded and ready for color. I still need to order some 4 ounce bottles of blue and black and replenish my Stix It pint, nearly empty.

I have done white before on a Cub and it too was transparent and took several coats before fully covering, where the Rand-O-Fill covered completely in 2 coats. It blended very well too, no brush marks, can't say the same for the white. My yellow Cub has no brush marks, but has about 8 coats of yellow! If the top wing covers in two coats, then I know the trick, if not, well, keep trying.
