I'm in the midst of putting together my second (and hopefully more permanent!) ROTJ suit, and it's my first time doing any amount of rattlecan work. I'm aware of how to do masking, layering, the stencils, etc... what I'm not clear on is the actual technique to use for each layer.
I prepped each piece by trimming and sanding down to 600 grit, which made everything nice and smooth. However once I put on a light coat of krylon primer, things were no longer smooth.. they felt quite rough and gritty. So, I lightly sanded with 600 grit again, put another coat of primer, and sanded again. I've now put a light coat of silver, and while it's certainly not at gritty as the primer, it's still not smooth. Should I be sanding lightly between coats to keep things smooth, or just keep layering and hope the clear coats even things out?
Naturally my concern is that if I sand the coloured paints, even lightly, that it will dull and score the finish. I'm aiming to replicate some of the amazing paint work done here on TDH, but feel like I'm missing some fundamental thing.
I'd appreciate comments and advice!
