No bro!! i read a lot on internet and also seen on pakwheels Yawar bhai has done sound deadening using jumboolon but i am not convinced. because in rainy season as it was last week doors are filled with water.
You have also observe a tiny hole on the bottom of doors that is for water drain.
No offence but if you use jumboolon water will stay there even a little but a some water is enough for rust and in case of foam its worst than jumboolon. So its not possible to open doors after few months to check for rust.
So what I did is that as there is no worry of water in trunk normally so foam is best for plastic panel jumboolon for inside trunk then Seal & Peal so that if water enters in trunk it will not come in contact with foam.
For doors my advise is to use seal & peal , as it is not available in Pakistan but you can easily import it through www.homeshopping.pk. they will import it for you. I got it from my relative who brought it from UK.
Soon I will post the pics...
