discussion Paint pits

[John]

I've started the Italeri Transit van which is white, I've primed it with a white primer and I wanted part of it to be white, I couldn't see if it was covering right and I've put a little bit too much on and it's pitted, I don't want to remove it and start again, can I sand it before putting another coat on? If so what is the best grit to use?

I would think as long as it is cured properly John you should be able to rub it down. One of the fine grits in polishing cloth sets would do it (I think). One of the car builders on here will be able to give better advice.

If it's pitted what paint did you use, halfords do something called bariacoat, which is supposed to prevent reactions of dissimilar paints, maybe you could use that first.

Tamiya coarse and fine compound should do the job might take awhile, I've used it in the past to get rid of the orange peel look. Or a super fine polishing sponge go slow go careful and all should be good.
Hope the above is of some help

If it's pitted what paint did you use

Stynlerez primer and Ammo paint, it's pitted because I've gone a bit overboard with the spraying, I suppose I could rub it down and prime it again, stynlerez is supposed to be self levelling, I just wanted to avoid that if possible and didn't know if a fine grit would smooth it before I put another coat on.

I've rubbed it down to a smooth finish and re-primed it, it's done it again I think I've still got cleaner in my airbrush, I'm going to flush my airbrush with warm water and try again.

I remove all the paint, give the kit a good clean and primed it again, so far so good, then I put the white on and it happened again, any ideas?

Hi John, I am nowhere an expert on painting but it looks to me as if there may be grease or something on the surface.

It does, but it's on top of primer, and although you can't see it under the masking tape the yellow is fine

The white colour is always a pain!!

The few models that I used the white colour, I've done always the same:
First, add the primer coat, a light grey from Vallejo.
Second, another coat of primer, this time a light sand colour, that I use as a preshade as well.
The last step I used a mix of white grey and normal white as a final coat (Vallejo as well).

If you are not sure if it will works, try it on a simple piece of plastic before.

Thanks Polux, the first time I tried it I used white primer and that was fine until I put the white paint on top, I don't want to strip the model again so I might use a primer again, it's going to be mostly covered in decals so the finish doesn't have to be perfect.

Has anyone tried the AK primer with micro filler? I'm just wondering if that would give it a better finish.

I've fixed it, AK paint stripper I'm going to change my plans and not use white.
