Josh, wow that is truly the barn find. Your grill is your life, but I would clean up and not do any painting or mods at all on that one.
Also after using my 2000 for 27 years 3x week, I can count the times on one hand, I even folded up the shelf during cooking for space. Mostly wow that is cool wood, the table lifts up but not for needing space
If you going to use this grill, I would seriously use the Durwood. Mine came with wood and have made 3 sets of replacements as they are not that durable if you are a messy cook like me. 1st set I used used composite decking and was way more indestructible, I assume like durawood since I never cooked on Weber version. None of the wood finishes like hot, or greasy things resting on them.
Yes, I could be a more careful cook, but I am old and not too trainable.
I purchased 2 sets for the current rebuild, these are the perfect size they cover the wood and Z-metals
With your attention to detail you probably take better care of your toys, and wood sure does look cool.
Just sharing my experiences of using/abusing this grill for decades from a tool vs a classic car that never leaves the garage.
