bro what the most effective for reducing tyre noise? i know best location is in the fender area..but which material is the most effective

Pinjam someone's picture.
This is how I soundproof-ed fenders. Most of the people will take off the fenders just to soundproof, but with my method the fenders stay where it is.
You can replace the Suppression pads area with those butlyn kind, but you definitely/advisable to take off the fenders. Because those kind of materials, you have to apply pressure to it to get a better effect...or else later got air bubble then the effect won't be nice...

whats the best way to reduce the heat from direct sunlight? heat proof which part? how much all together
Actually you can try doors and roof. I did mine and I noticed the most effective part is the roof. But I do soundproof along with heat proof.
I used Suppression Pad and Insulflex. Now my Myvi is much cooler than Honda City.
But I have something for KIA Spectra roof foam. It is 2mm thicker than SuperLon and Insulflex, but the compound is really much firmer.... the disadvantage is just that it is pre-cut and smaller size than 3'x4'. The thickeness is 12mm and around 36"x32" in size.
You can try this if you don't really mind about the size/price ratio.
