Let me guess.....new ride eh? 

Then a note to remember:

A good quality coating that's easy enough (*almost* idiot proof) for an inexperienced hobbyist to apply would cost around RM300 (product only)...but that's the easy part. The more difficult and time consuming part would be the preparation of the paint before the application of the coating. Remember, a good quality coating would last for years (if properly maintained) so you'd need to get the surface preparation correctly (unless you don't mind sealing some of those imperfections/defects under the coating).

Secondly, I couldn't stress more on the importance of PROPER and REGULAR MAINTENANCE - proper washing products, tools and techniques. Else, all those money and time spent for the coating job would literally be flushed down the drain in no time. So, I would strongly suggest to read up on MAINTENANCE as, personally, I would consider it to be the most important part in detailing and car care.

Well....errr....if you put it that way...then basically...yes. And that alone would roughly take you easily around 2hrs ~ 3hrs. But, actually, I thought you were talking about 'coating' but then it's sealant and wax. In detailing terms/understandings, you're actually talking about three different products for paint protection. Go slow bro...go slow...

Read through those articles as much as you possibly can first la....or at least learn about the basics first and get the facts right. Afterwards, if you have any questions, no matter how silly you think they are, come back and ask. Plenty of people here would be kind enough to guide you.
