An old CA bottle with a fine or small plastic tube inserted works well for rivets and is less painful to use than a syringe. The slightest presure on the bottle will puff out a small rivet. If you lay the tip on the surface horizontally will produce a different style or shape rivet than if you come from above. After drying the rivets shirnk but in my opinon or too round or tall. I usally come back across the top of them and lightly block sand the roundness off giving a a flat raised look.
