Ram-bro, for rivets like this I use solder machine with constant temperature. This is very important...







As you can see, temperature is about 300 degrees Celsius.


Second important is put a few layers of filler on surface on which you want to add rivets. Surface must have thickness. If filler is thin rivets will not be nice, and deep, and paint can fill it...

The most important thing is this operation is saw blade.



On the bottom I glue 2mm balsa. Balsa don't scratch surface, and raise saw blade from surface, so you first lean tip of solder and than gentle push it in surface...







Saw blade you can flax, and with that follow form of surface on which is adding rivets...


Who know, maybe is patience most important...
