Hi all,

Spraying my lip spoiler at the moment, using a compressor and spray tool. I think the mixture is too thich no amount of adjustment seems to prevent orange peel or the other extreme dusting. Need to get some cellulose thinners I think is that right?

Anyway I can sand the peel flat but my question is do I sand flat then apply lacquer sand, polish. Or do I sand, polish then lacquer my worry is if the paint looks dull under the lacquer I will never get a good shine to it.....is that sound thinking ?

What kind of paint? What size nozzle in the gun?

Paint should be mixed 50:50 with the relevant thinners.

Spray at around 30psi, with a distance of around 30 - 40cms paint a wet line then move down and do the same again overlapping the previous by around 50%

Once that is done you then lacquer, depending on the lacquer it gets more complicated to mix.. you cannot flat the basecoat down prior to the lacquer.

Its mettalic paint 47a from Halfords I was told it woudn't need thinning as its what they put straight into the cans. Looking at the viscosity it seems a tad thick it pours off the stirrer rather than drips if you know what I mean. My technique seems to be ok and pressure is about 4 bar.....So I can't flat the final coat of basecoat before I lacquer? so the last coat has to be spot on ?

try some thinners in it then

It should take around 3 seconds to stop driping off the end of a stick.

basecoat can even be dusty as long as it is even.. lacquer makes a big difference.

As David says your problem is you need to thin it.Adjust the gun to so that there is a nice fan of paint coming from the gun and go and get yourself a tacky rag from a paint suppliers.When the basecoat has been left to dry rub the cloth over it to remove excess overspray and dust.This means the lacquer will be smooth and there will be no build up of metallic particles under it.
