3M Underseal - How Much I Need?

[idoari 10]

Hi,

 

i want to remove the factory underseal and replace it with the "3M Body Schutz Rubberized Coating Black - 08864" .

it comes with a 1 quart bottles - how many bottle do i need to coat the entire undercarriage and wheel wells ?

i pretty sure i need at least 3 bottle and no more than 5 but because this product is not exactly cheap and i need to ship it to Israel i want to get the closest to the actual amount i will need.

 

thanks

Ido
