I hurt my car butt while putting groceries into the boot. Dropped some heavy stuff on the butt and now got bad gash

I'm thinking of using the touch up paint eventhough it'll will not give a good result. Checked professional touch up costs more than RM50. With that amount would be enough to buy the touch up paint and can use for future injuries.
Trust me and take my advice. If you did not perform any DIY touch up before , dont do it. Will regret like me later if it goes wrong
Professional touch up paints are better than the cheap touchup because their basecoat + clearcoat are more durable and dry faster + no need wait 24 hours . Maximum only half day will get it done ( appointment )
Some people managed to do it easily maybe is because of their area is not hot or humid. Unless you can do it in room that fits a car inside. Because if wind blow will make paint go wrong then if too hot sunny and humid will make color
darken , the clear coat looks ugly as well.
I was told that go car foaming will fix the vibrating/rattle issue on the car but have not try it yet. But if i am going to go and do it , i will probably tell them check whether any screws loose before foam. For the air cond vent, some guy say apply some kind of special glue that will adsorb vibration. Actually by right the car should come with this special glue just proton quality is poor. They only snap plastics and done
