I had a full respray on my white 300ZX 18 months ago, however, just recently the paint in certain areas has gone very rough and looks almost as though it has has a fine layer of frozen water on it.

 

I Have washed and dried the whole car and concentrated on the affected areas with a bodyshop friendly paint cleaner but it has made no difference.

 

What has caused this? Is the paint knackered? Is there anything I can do to prevent further paint deteriation? Can I have the paint flattened back to how it was or does it need another full hit?

 

Cheers guys, Dan

Sounds like you've got a bit of oxidisation on it. Nothing a buffer will sort out and, at worst, a colour sand.

 

If you don't want to tackle it yourself, then there are plenty of good auto 'detailers' that will measure paint-thickness and use various techniques to take the paint back to the good payers and protect it with a high grade wax.

you need some G3 buffing compound maybe a bit of p1200 wet and dry ..

start with the wet and dry rub out the lumps dont worry about scratches they come out ..

once paint is flat using the g3 and plenty of water and a buffing circular sponge get buffing once it looks greasy stop wipe down and dry of ..

get some autoglym and smear it on with ya hand rubbin plenty into paint let it dry..

now wipe of access ... check results and repeat proccess if it loks cack....

dont go maD with the wet and dry and remember to use water...

if you want a real fine cut use g10 compound then the glym...

its a white car so you have the easiest colour to hide impurities ......

Could you do this to old paint?

Could you do this to old paint?

 

Absolutely... a great way to refresh an old dull paintjob.

yess if your car has any odd bits looking crapp rub it down saying that you need to be very even when doing so especially on a white or red car as white goes yellow in time and red pink .. if you had a red car with shed loads of white oxy it can be removed with wet and dry 1600 and a good rubbing block .. once you find your origonal colour get out he g3 then the g10 then the autoglym ..

a perfect solution for the poo painter who dribbles and ends up with runs ..just rub em out ...Its called flattening the paint job ..seriously ive seen some terrible paint jobs salvaged using this method ..although you can get the car a new clear coat once rubbed back to origonal colour.. really would bring an old paint job alive again../

Someone has mentioned to me tonight that what I am seeing is orange peal caused by a poor preperation for my respray 18 months ago. Does the same method of restoration you guys have already mentioned still apply to this "orange peel" effect?

Yes but you have to be so carefull not to brake through the paint :(

Get a sanding block and use the same method to flat out the orange peel, but dont go to mad as you can go through the paint!

and try and stay away from the edges as paint is a lot thinner there

Get some pics up, tbh the way youve described it it sounds more like micro blisters within the paint rather than orange peel.

 

Orange peel can be sorted using wet and dry, you want to start with something very very weak, ie 3000 grit. You always start with the weakest combination and see where you stand, then step it up if it doesnt have the desired effect.

 

Microblisters on the other hand are a different kettle of fish. If theyre in the clear coat, you should be ok if your VERY carefull, if its in the colour coat, the only solution is a respray.

Another little tip,

use a sanding block with wet 1200 or higher grit and a bar of soap, wet the paper then coat it with soap

Orange peel is not caused by poor prep. Its caused by poor paint application when the job was done. it doesnt "appear" later.

It WILL be easier to advise you if you post up some pics..

Yea, I think it is microblisters that I am seeing tbh, I will get some pics up asap anyway

Be careful withe wet and dry, for me 1200 is too rough especially if you dont know what your doing start with no more than 2000 and if you can get 3000 better still. I really wouldnt suggest wet sanding unless your really confident. As Si says, get a good local detailer to do a paint correction. Expensive but not as expensive as a paint job if you cock it up.
