I did that from a AC Technician some 4 year's ago.. I simply gave him the keys and left my car at his work shop we used to do all the AC work from him so left the car with him...
He insulated the whole interior roof, floor, boot, firewall, door's.... He got that sheet from some scrap yard the sheet was like one layer of foil paper one layer of foam one layer of some rubberised material. And used that all over the car after that day the car remains noticeably cool.. At that time all costed us some 7000-/RS including his labour and the cost of that sheet and the time he took almost 9 hours to finish the job..
After that i didn't visited his shop for some 2 year's. 2 years back i again wanted to insulate another car from him when i went there i came to know that he has shifted to some other city...
Then i met another mechanic he recommended to use diamond jumbolon but the results of jumbolon aren't that good just felt a 10% difference...
