TIPS NEEDED ON PREVENTING LIGHT LEAKS IN LIGHTED MODELS

[BERT aka MODEL MAKER]

I an lighting my PL seaview with LEDs and want to prevent any light leaks or light shining through the sub. I am priming it with tamiya fine white primer, followed by a couple of coats of tamiya medium gray. the sub is molded in black plastic, think i need to use the white primer a little on the inside hulls to prevent light leaks and light shine through the plastic ? OR will priming the outside and painting with the gray prevent light shining through the solid plastic sub body ? I am puttying all seams by the way.

Silver or any metallic is very good because of the opaque particles of metal in it.

thanks, i have some metallic silver left from my other project. I guess an inside color will prevent light shining through the plastic.
