How do I extend my drip edge?
If the gutter is mounted too far below the drip-edge, or if the kickout doesn’t extend far enough over the gutter, a retrofit solution would be to slip a strip of metal or rigid plastic flashing under the vertical fascia leg of the drip-edge and let the bottom edge of the strip overlap the back edge of the gutter.

Which silicone sealant is the best?

Can I use silicone instead of caulk?
Silicone is highly elastic and will adhere well to any smooth surface. Because of its elasticity, any movement in the joint should be tolerated and the silicone won’t tear. That’s why it’s better than acrylic caulk for larger joints. In bathrooms only use sanitary silicone, which contains a fungicide to prevent mould.
