Big Green Egg rehab

Hi folks.
I just acquired this, which I think is a large BGE. $125.
Going to try to whip it into shape. See the link:

I was wondering what you think I should do (if anything) regarding the crack through part of the lid. Squish in some JB Weld??
I do hope to do some high temperature cooks, as well as the low & slow stuff.

Any other suggestions (including repainting advice) are also welcome. Also, if anyone has a serviceable used large firebox they want to sell please let me know.

I did post this on the BGE forum, but it pretty much got swept away with the tide of new threads. . . .

Thanks, Steve

I agree the high heat cements apply easily and last a long time also High Heat Paints are readily available in many colors and some are even textured so you can get the kids or the missus to help with the "design". Restoration is useful and fun and when you're done hopefully you'll have a place to Park it. Congrats on the rescue and have fun!

Update from the OP:

Thanks for the info, guys.

Yeah, I heard conflicting opinions about the make of this kamado.
A BGE company rep said it looked like one of their older models made of "fire clay" instead of ceramic, and meant to operate only up to around 400 degrees.

My final decision is not to work too hard on the rehab. I am going to try to jury-rig a new firebox out of some terracotta pots, and use it for "low & slow" cooking until I re-sell it. When I do re-sell it, it will be with full disclosure.

BGE or not, it is basically a clay kamado.

If anybody has an extra firebox they think might fit, even if used & cracked, I'd be interested in buying it if it's cheap.

Thanks again --

Steve
