That is not a job for somebody without experience! If you really want to DIY, you could look at a few videos in youtoob and experiment on painted tin cans or a piece of wrecked fender. If after considerable time you then think you can do it yourself, it will be a lot of work. Good luck and may you have all the endurace you need!
