well the weather bomb turned out to be a bit of a weather blank so far at least

No snow here.
But seen a few cars covered in couple of inches of snow - cant be local drivers ...

Glass sealants are fantastic for helping preventing frost from sticking

I use AD GhostRider myself, and even heavy frost struggles to stick. Even when it does, I pour cold water over, which almost instantly melts the frost, and due to the repellent coating, water runs off before it can refreeze

Silicone is every painter nightmare. I hate it. Silicone reaction from car wax etc.

Use peanut butter oil or a plastic sealant like werkstat prot.

Using penut butter to get rid of frost ? That's a new one

Right, time for another daft question,

Frost can attracted mosiurse, and within time can cuase rust ? correct

As ironic as it sounds... water does not attract water in the sense you are describing.

Frost is moisture. Just frozen.

I didn't mean it like that mate,

That's why I'm glad you're here mate, if I need any of My college work going over or correcting, I'll be contacting you, not really, I'm not that bad

I know if water hits bare metal, in time, it will start to rust, but, break it down for me in a simple way,

I know that, I just realised worded it wrong

The penut butter thing, explain that one to me

In what other way can you mean it then?

I think you are meaning capillary action then, but that is between materials and liquid, rather than water-water etc.

In simple terms though:

Water deposits onto iron.
Water reacts with atmospheric CO2 to form carbonic acid.
Carbonic acid dissolves iron.
Water begins to separate into hydrogen and oxygen.*
Free oxygen bonds with dissolved iron, electrons are freed, rust happens.*
Electron inbalance = formation of an anode/cathode, electrons flow back to good iron.§
Process is repeated, powered by electron chain (anode-cathode) and electrolyte (water).

** is sort of simultaneous with § (look up electrolysis of water)

Peanut butter OIL.

Oil structure is generally like this:

The tails with the H density interact with the surface, leave the other end (head) exposed to the water. The tails are hydrophobic so create an area of zero water density, whilst the head end with the O on it is negatively charged, attracting water. It basically makes a barrier.
