Paint and primer scaping off and Future removing paint?

[Deleted]

Afternoon all,

I just came across an issue on latest build. Two issues actually, one being that the paint plus the primer can scrape off the model.  granted you have to go out of your way to do so, but I've never really experienced this.  I am assuming since this is an all resin model, the primer (MSC acrylic paint) just aren't going to be friends.  am I right or wrong on this regards?

Secondly, using Vallejo paints, I hand brushed Future on the model and in some sections, the paint actually came off.  I've airbrushed Future before with no issues, but this is a first I've seen of paint coming off.  has anyone experienced this before?  I almost want to just write this off as a fluke.

I don't have any experience with resin kits,but it sounds like there's still mold release on the parts!Did you wash the parts before painting?

Not a complete fluke. Acrylic paints do respond a little differently with resin than with plastic...even worse with metal. When it comes to resin, washing is a good start, prior to painting. There are release agents left behind sometimes that can wreak havoc with paint in general. (basically what Leon said )

When applying acrylic primers to any parts, especially resin, try dusting one or two quick coats onto the surface. You will still see the base parts, but the primer will bond easier and quicker to the surfaces. Then apply you fonal primer coat to "fill in the blanks" so the speak. If you are looking for full coverage with the pimer, be aware not to go too thick...heavy with the application. This will effect the curing time. With Vallejo, the primer should be cured within 12 to 24 hours. After that, the primer and paint should be hard as nails. Depending on how thick the application(s) are, if you work the area...weathering or even Future, you could run the risk of removing paint.

I have been know to dust a couple coats and let things dry for a couple minutes, add the top coat of primer and then use a hairdryer to almost accelerate the curing time. Be careful not to get to close as you would figure. The primer and paint dry quick and you can keep going. But....you will want to wait a full 12 to 24 hours to allow it to fully cure. With this method, I can paint resin and scratch it with my fingernail and it does not come off. All about the cure!

I washed and soaked the model prior to building, but then again it is my first resin model. Thanks all for the heads up. This is great info for when I build my BSG Viper MKVII with a BHP VIIE resin upgrade.

You're welcome! Due to the fact you hand paint, you may want to consider using some decent auto primer (Rattle can) to lightly prime the model before painting. It will help with this dilemma greatly I think.
