Default Kill the sound and heat

So initially I was going to just recover my headliner. Pulled it out about a week ago and during the process figured as long as I'm doing it I might as will put some heat and sound deadening up on the roof before I reinstall.
As with everything I am researching it to death so I need some opinions.
All kinds of options out there
Home Depot brand
Dynamat
Eastwood brand
Lizard skin
And many more.
Then a choice of stick on or paint on.
Has anybody done this and if so what did you use and what have your results been. I am looking for a decrease in heat and good sound deadening qualities.
What say you and what do you recommend?
Looking to do something fairly soon riding around with no headliner makes for a very noisy hot truck

Do not do the Home Depot foil backed asphalt. It is a waste of time and money and it will stink for at least a few days.

IMO your best bet are SDS or Second Skin products, and use what they recommend to the point it fits your budget and amount of effort you want to put into the project.

Second skin is amazing, but spendy. Still your best option, but too rich for my blood. A cheaper option is Ballistic Hollowpoint. It is made by Metra, and is nearly identical to Dynamat, but with a more reasonable price. Remember that damping material reaches peak efficiency at 30% coverage, so make that your minimum. I usually shoot for 50%, just to be safe. More coverage is better, but with diminishing returns. So you can save some money by not covering everything, and stretching resources. That will dampen panel vibration... but then you want a closed cell foam product to cut road noise. (Second Skin makes a product that does both). I've even used yoga mats I bought on clearance. Yoga mats and camping pads tend to be closed cell foam, and sometimes you can buy them cheap. Then get a high quality contact adhesive, and install it over the damping material. In this, more is always better. One loud area without insulation can spoil the effect easily. Boom, you have a quiet ride, for cheap. (ish)

I used lizard skin. Material cost me about $350 for sound control and the heat control. Took me the whole day to tape off areas I didnt want it sprayed. Lay down about 4 coats letting it dry in between coats to build it up nicely. I sprayed it everywhere in the cab I could get into. Then used foam mattress material to fill large voids and used pillow stuffing to fill the smaller areas. Its still a long way from being on the road but just tapping on the side panels outside, it made a hell of a difference. As these trucks sound like tin cans without any kind of sound deadening.

I got 2 gallons of each. Only used about 3/4 of each bucket. Have some left of each at this point.
