I would suggest you start with a simple project and Learn about How to apply the types of finishes you want to use first.
Get an old 22 or even just plain scrap steel and practice your finishing and Masking procedures first before you attempt on the gun you are trying to dress up.
There is an Art to getting the spray finishes to look right, and they are too expensive and Durable to try and remove if you are not satisfied with your work.
They may Look like regular Spray paint, but there is a trick to applying them, and it mostly is in the Preperation , and Masking if you are only doing a Partial job like your sights.
TIP
All moving parts should be Removed from the gun and parts you dont want coated be carefully Masked off.
IE: the gas tube lever.
