Thank you all of you guys for your response, your feedback is very value able to me like members (xulfiqar sb, nadeem nabi sb) praise from other members also does not hurt at all :D, the fact that so much people are in touch with me offers me solace, otherwise i have been terribly alone. No one understands me, they discourage rather than encouraging.
And xulfiqar sb i have read you mentioning under body wax many times, can you be specific about it (what it is) currently i am going for putty to seal off crevices of underbody undercoat and white paint (matching upper body).
I know underbodies are coated with (refined asphalt type material that our local people call compound) I could feel it when i was using the steel brush on grinder to remove old paint. But after market asphalt mixture is not of that good quality its just like paint. And the non professional way used to apply it it doesnt reach or seal off the surface smoothly. And secondly being a mixture to keep it applicable paint does not hold on that good on it.
Your advice shall be highly valueable for me. And i would also request other seasoned people or with knowledge to guide me.
Stay blessed
