Need help on paint shop

[ck318ci]

Hi guys, I am going to send my car to CYF paint shop in Kg Subang soon once the body kit is fitted. My quotation is RM3.2K for using Glasurit all layers, using good sealant. Total of 10 layers with 10 years warranty.2 times total polish/wax complimentaryColour of choice will be BMW M series Carbon Black. Problem arise when a good friend ( auto electrician) told me that the outcome from this paint shop is not as good whereas I have read and seen one of forumers car done by them of reasonably good finish. Questions: Have anyone get a paint job done by them? remarks?What is a the actual code for BMW Carbon Black? CK
