Effect of frost on wax/sealants

[scarr89]

Just walked past my car on the way back from the cruiser and noticed a light frosting on only my roof and no where else...

1. Why was it the roof that only had a layer of frost on?

2. What effect does frost in general have on any LSP layers?

Effects will be minimal tbh as wax can withstand a fair amount of abuse from natural elements before it starts braking down,
Sealants are synthetic and to a point are pretty hardcore (obviously they don't last forever) and can stand more grief than waxes.
