Not specifically a 20mm question, but the models that are my immediate problem happen to be 20mm. How do you repair resin models where bubbles in the moulding process have formed at the corner of an item such a fender. So the corner of the fender is missing, a circular how is there instead where a bubble formed in the mould. I have tried various fillers, looks like it might work but as soon as I try to gently sand it the filler falls out – there isn't a great deal for it to adhere to but clearly it isn't adhering at all. Wonder if you have any tips other than leave it to look like battle damage. |

Put a little superglue in the hole and then fill it with filler. |

I've used Kneadatite (2 part epoxy putty). Works pretty well. Make sure to completely fill the holes, maybe even leave a little extra to be sanded later. |

Milliputt is your friend, standard is best for this sort of thing.

Do you have room to glue a small square of thin metal or plastic under the fender? This would give a shelf for your filler to sit on. Keep it back so that it won't show at the edge. |

Not really. Talking about fenders on small german tanks in 20mm (PZ I and 38t). It really is a bubble right on the corner but becuse the fender is so small it is quite noticeable and because it is circular it looks like someone has taken a chomp out of it. Because it was formed by a bubble there is a bit of a recess/cave for the filling material to grip to but not much. I think the supergrlue idea sounds possible. |

I have used blutack coated with superglue as a hardener for fender filler and am experimenting with superglue and bicarbonate of soda as an accelerator…..
In a couple of cases I trimmed out the curved break for a field mod cut fender/ mudguard. |

For small bubbles like you are talking about gel style super glue works well. Just remember to let it set but not too long. The longer you wait the harder it is to file it smooth. |

Battle damage? Cover it with stowage? I've done both in the past. |
