great answers above...
just want to add some basic stuff:

for me the first step to detailing is inspection... wash and wax and then inspect.
inspection is two part:
1. feel the paint- several ways to do this. i use the backs of my fingers (and actually also use the fronts- the backs are more sensitive though)- the way to learn paint feel is to use a plastic baggy. if the paint does not stick the paint is good for this step. if it sticks, then the paint has contaminents. the cure for rough paint is clay. kinda what i am adding here is that clay is not something you do just cause its "time to detail". clay is done when the paint is rough.

2. sight inspection- here you are looking at the clarity of the paint. any swirls or light scratches will tell you that something may need to be done. as mentioned, a glaze can help here temporarily. however to really remove these type of imperfections, polishes are in order... and a machine is pretty much a requirement. how bad the scratches/swirls are dictates how many levels of polish will be needed.

your megs product is the lightest polish made (all swirl removers are light polishes), and it is the perfect type of product to begin swirl removal with. so that is an example of a polish. an example of a glaze is this (yup thats my car in that ad- thats why i chose this as an example!!):

and sealants can be called synthetics or synthetic polymers- examples include zaino, klasse, full metal jacket, etc.

several of us top synthetics (at least a coupla coats) with wax (favs here are lusso oro and p21s).

Thank You wanabe, slanguage, and muttgrunt. You guys are so helpful and knowledgeable.

My first car was a Honda Accord 1998 and I didn't take care it properly and now its oxidize on the paint and scratches everywhere . I love my S2000 that's why I want to keep it clean and take care of the paint.

I'll be saving money to buy Porter Cable Machine next

 

That is such good advice. I love this forum as the main interest is detailing and since I retired I have a part time detailing business. I found the products and especially the how to advice at properautocare.com to be invaluable. I have a contact there now and he is very experienced and has helped me with some difficult situations you run into in this business. That connection along with this awesome forum has given me a better understanding of this art and I have been growing my business steadily due to the techniques and products I use. Thanks to everyone.

 

A couple of additional thoughts. Just as there are two basic kinds of protectants--synthetic sealants and waxes (typically made up of natural and synthetic ingredients)--so there are different kinds of glazes. The older glazes, like Megs' #7, are oil-based. They add a hint of wetness. The newer glazes, like Danase Wet Glaze, are synthetic based. They enhance gloss. Some glazes are also designed to hide defects (e.g., Poor Boys' Black Hole, Clearkote's Red Moose Glaze, and Chemical Guys' EZ Creme).

Glazes are applied after polishing and before waxing/sealing.
