Default Roughness in Body Paint.

I had given my car for service few days back and it is back. Today while I was washing my car I felt that Some of the portion of the Car Body has became rough. Even in the Wind Screen became rough. As if some another kind of layer is coated from out side. Dont know what to do ?

go back to the service center and ask them to clean it properly. your car must have been parked near the paint dept. They will use 1500 or 2000 no. emery paper and sand it lightly. No harm done.

Yup, it's paint that has settled on your car causing this.

Once i my building someone was getting some furniture polished in his garage and clear melamine polish had settled on my car. A cloth slightly moistened with thinner solved my problem.

Go with white_vdi's suggestion for paint smoothening. For the windscreen, use a thinner.

just use a cloth moistened with paint thinner or nail polisher remover (acetone) for your windscreen. Will remove the roughness like a dream!
Keep us posted on your experience...

The car must have been close to another car being painted, the clearcoat overspray has settled over your car. Take it back to the workshop and tell them to clean it up, it will involve roughing it down with emery paper and then buffing the panels. Cleaning only with thinner wont do much because in all probability the spray was premixed with an accelerator catalyst which hardens over time and is difficult to remove.

Your right. Thinner only for the windscreen which you can't sandpaper.

be ready for a car with all sanding marks though. i have never seen any workshop restore factory finish no matter what others claim - even when handsomely paid.

there are no sanding marks left. i got the same done on my car and there were no marks or anything after the procedure. you need to do it with a very light hand and its no big deal.
Sowmya is perfectly safe dont worry.

I agree with that, dont worry, if properly buffed there would be no sanding marks left. Thats standard procedure even when your car gets repainted completely and is a safe option.

This is not the regular brown sandpaper used by carpenters. Emery has a very fine grit and is used world over for final smoothening of any surface just prior to buffing. 3M fine emery is recommended. No harm done to paint.

Just for info from Wiki:

Emery paper is a type of paper that can be used for sanding down hard and rough surfaces. It can also be used for resistant technology purposes to give a smooth, shiny finish to manufactured products and is often used in the finishing of high-end watch movements. Similar to sandpaper, it is made by gluing small particles of the mineral emery (also called iron spinel or hercynite) to paper.

I believe this paint is not a normal paint. Its a burnish paint. I think some one was doing Furniture working and sprayed all over.
By the way any Idea how to remove this Burnish ? If I try to remove the thiner in the Body will this effect the Body paint ?

Yes, burnish can be removed with a thinner or nail polish remover (acetone).

I don't think thinner will affect the car paint. What you can try to do is, that take some thinner on a cloth and apply it to some part of the paint inside the bonnet (or somewhere where it is normally not visible) and scrub it vigorously to check if paint is not affected. Recheck after couple of days and if there is no change, then apply it elsewhere with a cloth. Wipe with water later.
You can use it on the windshield confidently though.
