Advice on how to fill a small hole needed

Hi all,

I’m currently building a model and the variant I’ve selected requires me to fill in a hole in the upper hull:

The hole itself is something like 0.5-0.7 mm in diameter.
I am thinking of applying some Mr. Surfacer (I have 500, 1000, 1200 and 1500 and wondering which one will be most suitable) with a small brush and then sanding it if necessary, then priming the model with Mr. Surfacer 1500.
Do you believe this could work? Any other suggestions?


You can stretch a bit of sprue and make a plug. When the glue is dried it is pretty easy to sand it flush.


If the hole goes all the way through, I would stretch some sprue to the correct thickness, cut it off, insert it into the hole and glue in place. Later I would trim it flush sand and then use Mr Surfacer for any final imperfections.


I’ve posted images of this method fairly recently. You don’t even need to stretch the sprue to the correct thickness - just let it taper as you pull. Test fit it and cut off what you don’t need, leaving a bit at each end to work with. Slather it with liquid cement , insert and twist as you push. I like to use sprue from the same kit. Be patient. Let the cement cure. Once you slice off the extra with a chisel blade, you often don’t even need to sand it as it’s completely invisible.


Thank you all for your kind answers!
