need advice on what grade paper to use i'm gonna have a bash myself if it looks **** i'll just pay a professional to do it. Up to now i've filled the scratch up and need to start flushing down to the rest of the panel.

What grade paper should i start with and finish with for the final coat. If it makes any difference it's vauxhall star silver 3 metallic paint so needs lacquering after the top coat.

Yes i'm a noob at this but have to start somewhere


thx for any help
 
I think you start at 800 and work towards 2000, but i might be wrong there.

I've been spraying metallic recently though, and was told not to sand the colour coat at all - as you damage the metallic finish. You purely sand the lacquer coat to achieve the smooth, glossy finish - and the more coats of lacquer you put on, the deeper the shine.

Looks like it's not going to be an easy task.

No harm me trying tho cause if i can't do it it will need doing properly anyway so might aswell give it a go myself for 1 tenth the cost of a proffesional doing it.


i'll take some pics tommorrow and do a progress on how i'm getting on
 
The key is in the preparation and getting the primer coat done properly. The rest is pretty easy.

Just do light, steady coats, sprayed from a sensible distance, let it dry properly, blend it with the existing paint nicely and make sure everything is well masked up - makes the job infinitely easier.

Am i aiming to get the primer coat level with the rest of the paintwork, then apply the top coat then laquer then smooth it all off?

Personally i'd flat the colour down too, makes for a much less orange peal look. Unless using a spray gun the paint doesn't come out great and makes it very rough and 'hilly' applying lacquer to an already rough surface will just mean more coats needed to get an even finish and more chance of going through the lacquer to the colour without realising.
 
Well just an update not going to well have the scratch now filled out and smoothed unfortunately cannot get a colour match i've tried 3 tins of genuine vaux paint and halfords custom mixed paint was a no go bless the poor guy he tried he made up 8 tins and came out to the car with me every time to try and match it better but it's a no go.

i've had a quote to spray the left side of the car at the vaux garage blending it in across the front quarter all the way to the back quarter at £300+vat which suprisingly was the best quote i had.Altho he said they can't gaurentee an exact colour match that it will be close and they will blend it in to the angle on the front and rear quarter to lose as much difference as they can.



Next time i buy a car i'm staying well clear of metallic silver especially vaux star silver 3

while on this subject who are without a doubt the best sprayers in the country both for stock and custom finishes
