Update -
I got some rosin, mixed it with thinner at about 60:40 ratio and pained the back of the PCB. And after a while it solidified and is wonderful. Thank you for the suggestion.
And BTW, If you are in Bangalore, rosin is available at a shop directly opposite of the avenue road Masjid, about 100 meters from the entrance of avenue road. He doesn't sell in small quantities, but its very cheap. Rupees 130 per Kilo Gram.
Best regards.
