I use the Rustoleum Spray cans that you get at home depot. I tried two different "silver / chrome" type paints when building the
Ohka. The Chrome paint seemed to do the job best in terms of a nice bright silver. Only problem with it is that, although it looks like metal when it hits bare foamboard, it looks more like Chrome when you spray it onto taped areas or stray patches of gorilla or hot glue.
Here is the front of the cans...
and the names of the paint on the back of the cans...

This is a pic of the wing, taken at an angle so that you can see how the taped aileron looks a lot more shiny than the rest of the wing.
