autofoam can make the car rigid also improve soundproof, but soundproof still cant be better than the higher pricetag car which their original soundproof is already good enuf to start with, also may make the car uncomfortaable for passenger

when i first bought alza back then, i was so determined to make the car soundproof as good as higher range car eg camry altis or civic accord.. joint alza official club to learn all the DIY and modification.. and the B pillar rattling noise just couldnt be solved, which finally understand that it was due to imperfection welding of the frame structure..

i wont do autofoam to the car unless:
1) i am not planning to sell the car
2) not for family car
3) for modification purpose

once autofoam, u cant really reverse them
