Here is the beg difference when it comes to heating up asphalt and butyl.

Both products will respons well to heat.

They will both become more takcy and initial adhesion will be impreoved with heat.

That being said if asphalt dips below its freezing point it will lose substantial adhesion and will REQUIRE the use of heat in order to active the adhesion properties. Basically you are melting the asphalt in order to get it to become sticky.

Butyl will respond well with heat, but WILL NOT REQUIRE heat in order to stay tacky at low temperatures.

They will both become more pliable with heat and stickier with heat, but butyl will be sticky enough WITHOUT heat to adhere properly and dampen vibrations without chance of it falling off.

The same can not be said about asphalt.

ok, so I guess I'll be getting the Spectrum for the inner wheel wells then. next question is how much would I need? do I really need to get the 5 gallons? was looking to do maybe 3 coats.

Remember its a small Mazda 3

and I will be spraying it on to make sure its even coats. already got an undercoating gun.

2 gallons should work real well!
