Whats going on here? Wet flatting

[pedrobedro]

Holding the gun too close to the surface can cause orange peel. About 8" from whatever you're painting and keep the gun at 90°, overlap strokes about 50%.

I remember many years ago an old guy who was sought after for his skills spraying cellulose.
His trick was prepare the car to the highest standard I have ever see, then spray coats of cellulose, letting each coat dry and flattening with well worn wet and dry between coats.
His argument was every coat required a perfect finish under it.
He would apply about 5 coats, then the cutting pastes and polishes would start followed by wax.
The finish was out of this world, a mirror effect so good it was at times difficult to tell what colour it was

I would say you haven't flatted it enough before polishing, which is no problem, just flat it some more. Yep they are the lows in the orange peel.

I'm guessing you sprayed it a little on the dry side, but again no problem, just flat it some more and polish it.

celly should'nt need more then 3 coats.ist coat lightish just to get colour.then two coats wet-on-wet.
spray at 45-55 lbs.pressure.and you could add more thinners,10%maybe.
when i started out i use to tape a bit of news paper to gun cup.when you can read it you have enough paint on it.
that amount of coats the paint is not thru dry and picking up on rubbing paper.
i hope you are using a good dose of washing up liquid in you water,that helps stop pick-up.
no where have you said what colour or if metallic your using.

Hello Ross,

I was told to put one coat (cellulose) on top of a previous before it had gone off (wet on wet) by a professional paint sprayer, but not six coats, the idea is to cut down on flatting.

If there is paint particles sticking to the wet and dry, it is too soft to flat and needs to be left for a while longer.

Hi Ross. it looks like a combination of too much gun pressure and paint going on dry, spray should be around 45-50, The paint isn't flowing once on the panel.
The bits on the paper are because with 6 coats it probably isn't dry all the way through, still soft.

What thinner are you using ???

I was extremely careful not to contaminate it so Im confident its not that.

I sprayed it like this as I read somewhere that more experience sprayers will get the paint going on as thick as possible to the stage where its on the verge of running in order to get the best finish possible

I used an Aldi compressor and the gravity gun that came with it so maybe if I used the same technique with a better gun it would have been alright. On the other hand I could have been doing something wrong or it was going on too thick like you said

I suppose these things will iron out with experience but atleast its turned out well in the end I suppose

i normally leave a panel a good couple of weeks before flatting off
this is probably a bit excessive but i like to do things on the safe side.

if i was you i'd leave it another couple of days and then have another crack at wet sanding with some fairy liquid in your water.

Im not a professional, more an amateur who has had similar problems.
When Ive got what you have its been paint mixed too thick to flow once on the panel.

Lower temperatures needs the paint to be a bit thinner, last time I did it the temperature was OK outside, where I did the work, in the sun, but the paint had been in the garage and was still very cold from the previous night.

(not paint applied too thickly on the panel but too thick paint viscosity)

Im sure theres people with more knowledge than me on here though.

6 coats of paint is way too thick.
