Hello

 

I have recently had my whole car resprayed. The doors were put on the car by the paint shop, but i removed them as they were getting in the way in the garage. Sadly, the friend who helped me removed them knocked one of the doors over, and it landed on the concrete drive... 

 

Thankfully the damage was not too bad, however there were some scrapes which took the lacquer and the paint off. I got a tub of the original paint from the paint shop, and I have filled in the chips with this (by hand with a small paintbrush). I then rubbed down with some G3 scratch remover paste. 

 

This has worked quite well at removing the bumps and the colour mismatch. However, as you can hopefully see from the pic, there is still some 'shine discolouration' present. The rest of the door has a high shine, and the areas where I have polished have a matt finish. I have only shown one area in the picture, but this is in 2 other patches on the door. 

 

My plan was to buy some spray lacquer from halfords and spray the areas which need touched up only. Is this a good idea? I worry that I will have another mismatch, and end up having to spray the whole door etc. Or will these matt areas disappear when I wax/polish the car? 

 

Any advice is welcome! I appreciate that these questions about paint are difficult to see from pictures. 

 

I could obviously take to a body shop, but they are all currently closed- and that would cost more!

As it’s metallic sadly will never be perfect, this is to do with the way the particles lay down in a different way from a brush to being sprayed, this will also make a different in what it is painted is it solvent based or water. Either way in a ideal world they should be sealed up with a lacquer but please what ever you do don’t go to Halfords and get a spray can of it you could end up with more problems and more expensive 1: being spray can lacquer is rubbish despite what people say (your never see it in a paint shop for a reason) 2: there is a chance it may react with the lacquer that is already on there and if it does pickle etc the whole thing will need sanding back and paint (time and money) 3: you really need to know what your doing to re-lacquer remember you just can’t spray it on and it’s fine it won’t stick as the surface needs to be scuffed de-greased to remove the wax or polish etc then once lacquered the whole door needs polishing etc

From the picture it looks like you have polished this by hand and really a mop is needs for a good finish, also what did you rub it down with as you need to use 1500 wet and dry or finer 2000, 2500 if you didn’t the cutter compound won’t cut big scratches.

My personal advice would be and considering you have just had you car resprayed by a professional body shop would be don’t try and cut corners you have spent so much money doing it then get it done right again (not using a cheap Halfords lacquer) build the car up and don’t worry about it to much and once it is done phone the body shop up and explain that happened and they should be able to sort it really easy, as you have some touch up etc from them this is great news they can drop some paint in to the chips etc then give the door a light coat of your paint (sometimes know as a drop coat) this is a super light dusting and once the whole door is re-lacquer again it should look as good as new and not noticeable at all, also this should not cost you a lot of money either.

Hope this helps

Hi

Thanks a lot for your detailed reply. I agree with what you said. I’ll continue to touch up and rub down the scratches, but will leave the top coat to the pros!
