best paint protection ?

[gazpacho]

Hi,

I am a new Yaris owner (Yaris T Spirit Hybrid) and also new to the forum. I wasnt going to pay the extortionate amount of money the dealer was asking to have my bodywork / paint protected and thought it must be much more economical to get this done elsewhere.
Can you recommend what product I should use to keep that "new car" shine and to protect the paint and bodywork ?
Should I go for a product that I can apply myself or one that is applied professionally ?
Any help and advice will be gratefully receieved

Thanks

John
