first the unfortunate, but taken care of news with a PSA.
*do not lay LizardSkin too thick on inside corners without letting it fully cure before the next coat*
i really wanted the lizardskin to help smooth and fillet the tunnel corners, so i might have laid it on really thick in those lines. those spots took considerably longer to dry than the rest by a lot, and as they dried, they cracked. everything was still stuck well, just opened up, so i took the same 3M seam sealer i had to them and filled em all before painting. should hold up well, move well, and help adhere it all together. i tried to press it hard into the cracks, and keep from filing in the lisardskin texture. i'm pretty happy with how it worked. no pictures, but i had to do both sides.
