>>9341565>fluorescence showing up through the paint layersYeah. It will only show up under UV, but it's kind of a shame to use fluorescent paints and not be able to take a couple of shots of the kit under UV light.
>prime it moreI don't know which kit you have, but generally speaking primer is not your friend with high-detail kits. The 1/72 Type 0 I did this January had specific recommendation not to use primer at all to bring out the best in the sculpt.
