Your truck is looking awesome already. I can't believe the difference from your 'preped' photos to your first coat photos. The coverage with the Brightside is fantastic.

When I do my painting I have a clean second 4" roller that I run over each 'finished' panel to remove all of the air bubbles. I don't use any weight with the second roller, I just gently and slowly move it across the panel and it ends up looking really good (at least until all of the dust and dog hairs etc start landing on the paint).
