lookin good buddy
the rcs mask grips to the shell alot more which can create static. aswell as static there may be some surface residue from your fingers or the mask.
just come out with rcs body prep, 1 or 2 light mist coats drying off between (only takes a second with heatgun in order for it to evapourate) coats on the exposed surface and yer good to go. works wonders.
