Hi Peeps!
I recently corrected the saucer phaser ports / pulse cannons on my EM 1701 Beyond Refit diecast (something I had wanted to do for a while now).
For those interested: I painted out the existed misaligned ports using Humbrol model paint (a gloss white mixed in with the smallest hint of flat black - to create an off-white / grey matching the base saucer colour as close as possible).
I then used a sharpie fine permanent marker to create ports again in their correct positions (essentially two dots each to evoke the shape of the cannon ports).
Finally, took a standard felt-tip marker (water-based) and coloured over the newly drawn ports, to soften the opaqueness of the permanent marker, and make it more subtle in hue. The water based marker was also used to give a shaded recess tone around ‘cannons’. Admittedly, water based markers don’t hold much sway on metal, however it does a good job of influencing the tone of the permanent ink on the surface.
TL;DR: IMO, my Beyond Refit looks much better with the correct phaser port alignments!
