Shivraj dont ever think that adding a coat of wax alone would get you a mirror like finish. It will definitely be good looking than what it is now. There are certain pre-wax process which needs to be done to get that mirror like finish like clay bar, scratch removal, swirl mark removal, gloss , wax & finally paint sealant. It also depends on how good your current paint condition is. Meguiars products are really good & worth the money you pay. You can get it even cheaper if you can source it from abroad like US.
