Just wondering whether anyone has been brave enough to use this clear coat product on their Weber carburetors. It's a direct to metal clear coat and claimed to be solvent resistant and capable of withstanding 2,000 degrees Fahrenheit.

So far I've used it on small alloy parts such as the thermostat housing, oil pump, distributor and "Lotus" logo on the cam cover. As aluminium tarnishes over time I wanted something to protect it (other than elbow grease!). Results seem good so far.

I've recently had the Weber carburetors that I'm currently in the process of rebuilding vapour blasted and would like to preserve the new look finish. I know it's a severe application with the fuel solvent and it would be a real pain to have to strip them so I'm wondering if someone may have done it before. If not I'll probably just chicken out and leave them bare.

As an aside because I read a lot of issues to do with Webers on this forum, I strongly recommend during rebuild to remove two lowest lead gallery plugs. Chances are you will find these galleries packed solid with crud as I did. The only way of clearing them is to use a twist drill. No way will any amount of ultrasonic or solvent cleaning clear them. These galleries supply the starter enrichment but if the crud gets higher other circuits could be affected. Cant stress it enough - blow some liquid (eg WD40 in a can with tube nozzle) down each gallery in turn to see that the liquid comes out the other side to ensure they are all clear!

I will try some. Eastwood has some good stuff.
This appears to be another.

Find out where the limits are, and start from there
