Cracks in my paint!

Post by jinx182 »

Hello everyone I have a little problem and i wanted to get some opinions on what i'm doing wrong. I'm building the PL 1/350 nx-01. After primig the model i used a can of model master metalizer (stainless steel). When the paint started to dry little areas with cracks in the paint started to on the surface. I sanded the paint off the effected areas and tried again and got similar results but in different areas. what am I doing wrong?

What type of primer are you using? Some primers just don't get along with certain paints.

How long are you letting the primer dry? I always wait a couple days unless my primer and paint are the same brand (or I know from experience that they get along).

How heavily are you applying the metallic paint? Several thin coats are better than a thick coat. If you need a wet coat for a smooth metallic finish, the lighter coats, once cured, can help seal away the primer coat.

Yeah, I think I am spraying the mtealizer on a little thick. I have to barely touch the model with a mist. If a spot starts look wet, the paint starts to crack.

Either your primer is crap and you aren't letting it cure fully. Or there is too much moisture in the air and it has settled on the primed surface.

I let the primer dry for four days but it did rain earlier today here so maybe that's it.

My primer also developed cracks.
But it was on the inside so I just gave it another coat to fill in.

I had put it on way too thick and that's why mine cracked.

I give up. I just laid my parts in a pine-sol bath. I'll try again in a few days With a different primer.

Model Master Metalizer is not formulated to be used with a primer - shoot it straight onto clean plastic.

If they're like Alclad II they usually want a gloss primer.
