I'm getting ready to do a touch-up on my Diner. The paint is worn through to the wood underneath the cup/right ramp area - a patch, mostly (formerly) orange, about 3x3" or so. I bought a set of Liquitex acrylic primaries paint (with black and white); I'll mix the color onto a piece of clear plastic and match it under full light before brushing it on. I'm not trying to make this a collector's quality pin - I just want to keep the wear from getting worse.
Before I start painting, I'm guessing (sorry, tl:dr) I should vac off that area really well and possibly do some very light sanding around the edge of the patch before painting. Once it's painted up, I'll mask off the surroundings and hit it with a few metered shots of triple thick... (I wanted to use triple thick because I need to seal a backglass too) I'd like to put mylar over it after all's said and done as the wear is a result of the area being hard to reach without major disassembly.
Anything I'm missing here?
Thanks.
