jetwash or hose
bugspray/prewash/snowfoam
You don't need to rinse the car before using a prewash/SF. I'd only do it if the car was heavily soiled.
jetwash
dry
clay
You also don't need to dry the car before claying - it's only going to get wet anyway. Also, if you use something like Bilt Hamber clay, you can use water as lubrication.
dry
paint cleanser
polish
Might be worth washing the car or in some way ensuring all of the polish residue comes off. Doesn't apply if it's more of a filler than a polish.
glaze x2 leave 15 mins between coats
sealant x2 again 15 mins between layers - well i do dont know if this is the best way or me being silly
wax as many coats as you want, i normally give up after 2 coats, and just top up every wash.
Depending on the sealant, I'd leave a lot longer. I found FK1000P did much better if you waited at least 48 hours before applying a second layer. Ditto with wax - you need to give it a chance to fully cure otherwise you get gassing.
When I did my winter protection, it was two layers of sealant and two layers of wax applied over four weeks. Car wasn't used much then, so it wasn't dirty between washes either.
