I managed to lose another kickstand plate, sooo…
The horrible paint crazing came from “priming” the bare plywood scrap (yes, that’s a stray hole from its previous life) with a specialty white paint intended for plastic lawn furniture; it apparently gets along poorly with the forget-me-not fluorescent red topcoat. Doesn’t matter in this application and uses up more of both rattlecans, so it’s all good.
Of course, after tucking it in the bike’s underseat bag, I spotted the lost plate along the DCRT: now I have a spare!
