@haroongral. brother exactly I was telling this that there is no technicality is involved in the process. Search paint sealant, royal shield in Google and you can make an online order to get the sealant at your place. Then you can do it yourself or get it done from normal polish guy.
Back in 2005, they charged 5,000 for Xli and 3,000 for cultus type cars. Check the prices and shipping charges online, if they are more than check with royal shield.
