>>5478238I agree with this 100%, avoid using blu tac, it can and will rip poorly-held acrylics right off.
For silly putty though, make sure you take it and run it through some warm, soapy water before you use it. I've found that silly putty is often coated with some oils / lubricant from the manufacturing process that can stain into your model's paint. Just run it through and kinda mash it around as you wash it to remove the stuff.
>>5478673Get some Tamiya extra thin, that would probably be the best type of glue to use for a pre-painted kit since it is so thin it runs along the seams very easily with capillary action.
