Okay y'all! I'm having problems makinng paint stick to my Typhoon models. I did as the Battlefront (BF) website suggested and gave the models a light sanding with very fine grit sandpaper. I then shot one with a can of Rustoleum Gray Primer. I then set it aside to let it dry for about two hours. I then ran my finger across it to check the adhesion and was rewarded with the primer coming off! AAURRGHHH!! So what do I do now? The BF website suggested using a Miliput wash to help with paint adhesion and to use an enamel based paint as it is supposed bond better with the resin. I'll try the enamel primer as I don't have any Miliput. If y'all have any other suggestions please send them my way. Thanks in advance and Salut y'all! Bruce the Texas Grognard |

Testors enamel. Sticks to everything. |

How strange. Made of resin you say? Must be an unusaal formulation, I've never had any trouble with paint sticking to resin (I use Humbrol enamel for undercoating). |

I assume you did the usual wash with warm liquid detergent to get rid of any mold release first. If not, you might give that a try, and then redo the primer. Not sure if they are compatible, but the plastic primer they sell might be useful as well. Double-check with others though, to make sure it doesn't have a chemical in it that eats resin. |

You could also try Windex window cleaner, it works great as a resin mold release remover. |

I had similar problems with Battlefront's P-40 Warhawks. The first thing I noticed was that the grey resin was very glossy. I washed them in soapy water first, them primed them with brush-on gesso, which is my usual technique. The gesso tended to bead up even more than it usually does. After several coats of gesso, I let them dry for a week. The gesso was still very soft and would scratch off easily if I wasn't careful. I painted them with Vallejo colors, and even after the paint had dried, it would still scratch very easily. Only after I applied a spray clearcoat did the finish harden sufficiently. Next time I'll try cleaning them with Windex and I'll use spray enamal primer. |

I assume you did the usual wash with warm liquid detergent to get rid of any mold release first. Yep, I sure did. I always give a mini a thorough scrubbing with Dawn mild detergent and an old soft bristle toothbrush before I prime it. This time I washed and scrubbed the model before and after I sanded it. You could also try Windex window cleaner, it works great as a resin mold release remover Thanks Major Thom I'll give the Windex a try. I'll go dunk the model in some Simple Green now! (sigh) At least it'll smell minty fresh. Once again thanks for all the responses. Salut y'all! Bruce the Texas Grognard |

I don't know if you ever got these painted. A lack of responses suggests that you did but anyway for you or anyone else having problems battlefront did mention it in their Typhoon painting article here: link Basically says to put some milliput basecoat on the plane because the particular resin they made them with makes the paint fickle in adhering to the thing. Luckily I opted not to buy BF's planes since I like my toys in all the same scale ;) EDIT – oh nevermind I see you know about the article already. I should read the notes a little harder (oops!). |

I use either concentrated Simple Green or Formula 409 orange. Let the models soak for a week in the stuff, then scrub with a gun-cleaning brush. You'll know the mold release is gone when the surface feels rough like a sharpening stone. Then I use krylon camo ultra-flat black for primer, it chemically bonds to plastic and resin. |

I wonder if Pine-Sol would work. Has anyone tried it? |
Lion in the Stars | 09 Jun 2010 2:33 p.m. PST |
I haven't. I'm a little leery of Pine-sol around plastics, it really softens them up. Besides, one of those Orange-oil based cleaners is often cheaper! |

Okay, I just found a bottle of something called "Orange Clean" in the closet. I'll try it. |

It's because your paint knows that they're in the wrong scale! ;) |
