i don't know if it strengthen or make the chasis worse...
i've heard cases from other forums...that during impact, the force distribution of the chasis was altered after using autofoam...
so what is your purpose? if you want soundproof..why not install dynamat? instead of putting autofoam?
Dynamat is for external surface..example, doors,roofs, whereas autofoam is injected in hollow section, such as A, B,C pillar.
Autofoam is effective as soundproofing, but very pricy
