Cracked part on model, help needed
Posted by xylvis on Sunday, October 07, 2018 11:01 PM

Hi,

 

I'm pretty new to this, so I just bought a X-Wing 1/72 unit and upon finish assembling,

I used the tamiya acrylic paint to paint a few parts, including the engine area, after which I applied the tamiya weathering onto it and I just learned that the crack on my engine might be due to insufficient time of curing.

But I suffer a crack on the side of my plane as well, in fact my another model sand trooper had cracks immediately after I applied the weathering onto it.

May I know what causes it? Am i suppose to apply a layer of protection? or was I applying too much of weathering?

Wow, that's crazy looking.  Did you paint the light area of the engine?  I looks like bear plastic to me.

I doubt the weathering is causing the cracks, it think it's just revealing them.

When I zoom in close it looks like the model iteself has cracked.  Look at the rib where the crack crosses, you can see that the rib is offset on either side of the crack.  What does it feel like when you run your finger across the crack?

Is this a bandai kit? If so the cracking is due to using a strong thinner when weathering. Bandai plastic is strange it happened to my AT-ST build due to my clear coat I used. I just ended up blending it in as battle damage. Google search it and you'll find alot of people that it's happened to including a guy on the rpf that had cracks come up all over his expensive perfect grade falcon build. They are very beautifully done kits but when it comes to weathering stick to using acrylic based products, Flory makes some excellent washes that works great for this situation.

Yet again, I find myself amazed at the information available from the minds of folks here.

I never in a million years expected a definitive answer to the OP.

This is for Clint ---> Yes
