Mark, keep the silicon. Years ago, LBC guys had to use Castrol LMA because DOT 3 would rot the low quality rubber used in the LBC brake components of the day. Silicon is as good as if not superior to LMA (which is basically processed castor oil). Silicon will not rot your seals or paint, has a high boiling point, will not absorb moisture and as long as you don't have it mixed with conventional fluid, you will be fine.
