ih ihave a spraying problem how much thinner to paint is needed iam spraying metalic is it also the same for the top coat is it also better using good thinners kind regards chris

 

Chris,

You will have to get a data sheet from the place you bought the paint.

As a general rule it would be a 50:50 mix for a good quality paint (ICI or PPG).
Less of a mix for the cheap stuff.

cheers dave iwill try and get a data sheet thanks chris

 

As has been said get a directive from your paint supplier, however as a rule you are looking for the consistancy of a good fruit juice ( one without the bits ) also whilst at your paint supplier get yourself some filters which you should pass the paint through once it has been mixed. ALWAYS!!! buy a premium thinner for the top coats.
Once you have a couple of coats on the car, you should thin down the mix again, cannot give you a directive on this its just a 'feel' thing! Sorry! But I would imagine the final coats would be a ratio of about 70/30 Thinner/paint, by this time you are just dusting the surface. Remember the first few coats are to 'key in' the surface and can be rubbed down ( even with a metalic ) however once you start the finish coats, try to get a smooth finish as metalics will not take a lot of rubbing back.
Then for the real work!!! The laquer! Buy the stuff that is already thinned, its easier. This must be applied as a dust coat, as it is so thin it will run, however you can rub down afterwards. Don't try to get away with anything less than 6 coats.
The only problem is that if done well on a panel it can show up the rest of the car.
Good luck.

cheers ivan thanks for the advice i will take on board what you said i agree its one of those things that hard to explain i shall be getting some practice in now once again thanks chris

 

don't mess about with single pack paint. use 2 pack laquer. its a lot better and will give a much better finish. 2 coats one lightish coat avoiding edges and holes and one good wet one.

 

cheers will give that one a go thanks again chris
