Thanks for quick reply.
The main things to remember is, coat with diluted catalysed mixture very sparingly.
You can dilute much more if desired to coat more projectiles with a thin stain coat each time.
Bake at your 375 F for about 5-8 minutes (depends on air ciculation being ideal)
Cool between each coat, and reapply same dilute mixture, dry and cook.
If you over cook, then coating will develop a yellow tan going towards brown. Smash test will guide you if you go too far or not far enough.
Dont forget, final appearance is cosmetic in majority. You will get much better at coating as you go. You will be coating in your sleep.
If you had applied 3 coats it should be adequate. Size to suit diameter of your barrel (none of the coating should come off) and go and shoot them.
Please advise how you go.
If you can provide me with a private message with your email, I can send you coating techniques which should be very useful.
