You need to do some bump mapping and a lot of tweaking

Filters -> Map -> bump mapping

some screenshots (quite large so not in line) and a quick run down.

Top is the door as a base layer (straightened with the perspective tool)
The paint splash extracted from the image and scaled (80%) then pasted into a transparent layer.
(important to have the layers the same size otherwise you get into a mess with the bump map offsets)

Bottom image is the bump map dialog, note you are bump mapping the paint layer and using the door as the bump map. This is the default setting, for any image you need to look at say light direction and adjust accordingly. Just play around with the settings and see what results.

next

Top image - you should get the paint layer impressed with the door layer contour.
Erase bits that would be under the grill, door handle etc.
Small areas that might not respond to the bump map try and deform them a little with the cage tool (not my favourite gimp tool by a large margin, but ok for small areas.)

Then it depends how much time you want to spend on your masterpiece. I would give the whole of the paint layer a small (2 pix) gaussian blur. Bits around the metalwork need a bit of effort.

A very quick trial to get the above screenshots. Missed the bit at the door sill for example.lol

Thanks bro for the tutorial.

However I am still stuck at the eraser part where if I use the eraser a big patch is eraser and the gap is big?

How can I go about to make as if the paint is at the back of the handle instead thanks for your help

May seems a noob question but I am unsure thanks

That is a bad start. You need to do some reading.
http://docs.gimp.org/2.8/en/gimp-tool-eraser.html

Things that might help.

You can use any of the brushes with the eraser tool.
It is much the same as the paint tool.
- resize the brush either with the slider or enter a size directly or use the square brackets ][ to step the size up and down.
- Erase in straight lines. Click on a start point, hold the shift key down, move to the end point, click and it erases in between. Very useful with a fuzzy brush but check on the brush spacing.

I do not think you will ever get it totally realistic, as before lots of tweaking, depends how much effort you put into it.

So here as well as erasing the grill.
bump mapping
blurring
embossing
lighting effects
dodge tool on selected bits .. and so on.

By the time you do all that, quicker to go and throw some paint on the door and take a new photograph.

best of luck

edit, missed a bit at the bottom again. LOL
