I've pretty much quite mixing my own a long time ago. Pinhole's are a PITA and yes when the primer goes on it will show all kind's of stuff.
System 3 Quik fair is what I use. You may still get a few pinhole's but nothing like you will with stirring your concoction's together.

Those TH marine hose cuff's are chrome plated plastic. I was actually going to try and wax/polish them today. the rest of them on the boat are just Black plastic.
There are 2 more Black one's for the rigging tube going to the crow's nest.
