Had one of those AHA !! moments today as I was applying more brick mortar.... I was still concerned that the factory walls had too much white tinting from the mortar application..... Decided I'd take 2 of them and clear coat them again to see what effect that had.
It significantly knocked down the white haze. I tried a new flat clear coat by Krylon, bought it at Walmart in the oversized 25% more can -- Name is Krylon ColorMaster - Clear - Flat Crystal Clear. It's much flatter than the Rustoleum Matte Finish I had been using, and it seems to be finer spray coming out of the nozzle. So for clear coating buildings and such in the future, I am going with the Krylon product. At $4.00 for an oversized 15 ounce can, it's a great deal, and it's dead flat.
Anyway a few more walls and inserts to mortar, then paint the windows/doors. and let the assembly begin !!! The walls on the far right, below, have the second and final Clearcoat applied. Tried 3 different colors for window/door trim, I am probably going with the dark red/maroon in the center.
