Ideal for winter time, last couple of cars I've done have requested this for longevity reasons over winter. Looks great on red too!!
I'd personally look at using Zaino Z3 - it's a man made polymer sealant, specifically designed for single stage paints. Will give you the ultimate gloss finish, and last for ~6 months. It's only £17 for 250ml I think, which will last you quite a while.
