Resin to Injection Moulded

[Guest]

Hi all,

Just joined this site as I 'am looking at getting back into scale modelling haven't done any for a few years. Anyway I have a couple of questions that I need answered for my up coming project.

I am looking at building the 1/48 Airfix Hawk 100 kit with the R&R Models upgrade for the Aussie 127 mark, so my question is how do you glue the resin parts to the injection moulded parts. I know you have to use super glue for the resin but I thought this would've melted the injection moulded parts. Second question is how do you paint resin parts as I tried this before but the paint didn't adhere to the parts. Any help/advice would be appreciated.

Moulded plastic parts often have some residue of the mould release agent on them, this is particularly an issue with resin parts. You will need to really thoroughly clean each of the resin parts - I use a bowl of warm water and some abrasive cleaner and a toothbrush at first to scrub the parts. Smaller parts you just need a detergent and warm water - make sure you put the plug in the sink and prior to emptying the bowl - count back in all the parts you've washed and do a sort of dry run to make sure all is there!

Regarding gluing resin parts to styrene - I'd assume superglue would work - but dont have any experience there as I've just built resin kits and styrene kits - without trying to attach resin to styrene.

I've found humbrol enamels to be much harder wearing than acrylics. Especially if you are using an airbrush - acrylics often dry in the air and you end up with a dusty finish which doesn't key well to the surface.

superglue is the way. yes it will melt the styrene. that is the idea. that is exactly what normal poly glue does, its melts the plastic to form one bond.

as for resin parts, as alan says, a good wash is always a good idea. also, if detail wont be lost, give it a good rough up with some wet and dry paper and give it a few coats of primer. if you can sand it, make sure you prime it. then even if you make a mistake you can remove the paint back down to the primer (as primer is a lot harder and more durable than normal acrylics/enamels)

hope that helps,
