Another TR owner here and yes, it is a great colour and by far the best flat colour I've seen. I've always preferred metallic/pearl but the way the red catches the light is great. Never fails to cheer me up when I see it
Anyway, I have very limited experience with wax/sealent but I have been impressed by FinishKare 1000P. About £18 for a good size tub and is high temperature resistant. Not sure how long it lasts exactly but mine is still beading well and I can't remember when I last applied it, definitely not this year though so I'm thinking perhaps October. Recently I bought some wax from the same brand called Pink Wax, also about £18. I haven't used it on my own car but I did on my sister's car a few weeks ago. Applied the 1000P first then the wax. The finish was really good, a great depth to the shine and bird poo just rinsed off, really looking forward to doing mine with it. My sister was amazed (mind you it was pretty bogging when I got it).
So, mine just with the 1000P:
And with the Pink Wax on top:
