After fixing up the header I disassembled the monitor bezel section to remove the rest of the white plastic parts. er... I mean BADLY YELLOWED parts
This was meant to be my before photo for retrobrite treatment, but it ended up being a big fail. I used the official instructions on the official website. the Xanthum gum flat out didn't want to mix in and ended up a clumpy mess even after 15-20 minutes of trying to get it to mix. I spread it on as best I could and reapplied throughout the day to try to keep it from drying out but it was no use. after a whole day in the sun I got a few blotchy light spots but no noticable change... cleaning that crap off was a pain too. So I opted to use White Vinyl Dye.
After a few coats of vinyl dye you can see there was a MAJOR noticeable improvement. Here's a comparison against my other Egret. You can see it still needs a few more coats here as it looks almost pink from the yellow trying to break through.
After a few more coats here's another comparison this time of the header, here you can see the "shine" of the vinyl dye is a really good match for the original plastic luster. Gloss paint would be too glossy.
And compared to the white paint on the cab:
you can see it's a bit brighter than the original paint, but on the cab these are also separated by the blue stripe so you'll never see a white plastic part right up against a white metal part.
Even still I'm tempted to take one of the panels to the hardware store to see if I can find a spray paint that's a more exact match... maybe when I get to painting the other Egret.
One thing I forgot to document was that the monitor bezel pieces had all of the screw posts cracked. One had a chunk fall off (thankfully still hanging on by a thread so not lost) and I repaired them all with Black JB Weld Epoxy... not too pretty but it's in a location you'll never see and i'd rather they're nice and well reinforced to last the life of the cab...
these little plastic screws not only hold the plastics to the cab frame but they hold the weight of the front glass... so they get stressed A LOT there's a reason they were all cracked.
I was also an idiot and did this AFTER painting and got some epoxy finger prints on the freshly painted surface... so I had to lightly sand that spot and then re-spray it.
