LS Aluminum prep and high temp clearcoat?

[64skylarkls1]

Hi Guys,

I'm working towards getting my LS1 used motor cleaned and installed in the next week. I'm working out of my home hobby shop. I would like to clean all aluminum surfaces like new and then clear coat it all.

What's the best detergent for cleaning all the sufaces? I don't want to use something that would keep a clear coat from adhering.

What prep needs to be done to the surfaces to get good clear coat adhesion to the aluminum?

What rattle can high temp clearcoat is recommended? I don't want it to yellow, as it will get a lot of use.

Also, what would be best for coating the stock LS1 exhaust manifolds?

Thanks to all!!
