On the paints I bought a qt of the Krylon high heat, I used this with a paint brush to treat the rust along the rim of the control panel and the large grease tray. Just a lot easier than spraying in a cup and you won't need to keep spraying paint in a cup if you did not do enough the first time. That paint was at Lowes was $15.00 a qt but cost effective if you do a lot of grills as you could probably do 40 of them with a qt. I also had a few worm holes in the inside of the lid so touched them up with the brush, not enough paint to poison you.
I used the Krylon Gloss Black for the bottom rack, the Side plastic frame caps, knobs and handle were sprayed with the Rusto Satin Granite Grey. Used the Rusto Satin Clear on the side caps, wheels and knobs. Used the Satin VHT High Heat on the handle should be okay.
Now I suspect this is marketing hype you see two cans of Krylon High Heat one max that says 1200 and the other that says 600. However if you read the specs they are the same good for 600 continuous with spikes to 1200 yet the max is 6.98 a can and the regular high heat is 4.28 a can which I used for the side caps and used the max for the firebox. I really can't tell much difference in the color or sheen will take a picture but on the 1100 will spray the frame, the firebox and the lid sides with the 4.28 a can high heat paint. I really like the Krylon unlike the rusto ultra actually has a nozzle that won't break your finger with out the trigger accessory.
I used the same gloss high heat clear on the Weber Emblem after it was done that Bruce used its more glossy but its fine as the VHT is Satin.
I have a lot of paint for the next project from all these cans so will probably only need to buy another few cans of the Krylon High Heat. Got plenty of clear and I use Rusto Satin Stone grey for the knobs on the 1100 which I have some left from when I did the 1000.
