Need suggestions for A/C hose bracket holes
 

I'm removing my A/C system, and am looking for ideas on filling all of the hose clamp holes (the ones underneath the car and in the left front fenderwell). I seen someone suggest putting the screw (with a bit of silicon) back in, but I don't particularly like the idea of having the screws there. Although I don't envision ever reinstalling my A/C, I'm looking for a solution that's reversable. Is just putting some silicon (or something similar) in the hole a viable option? What have the rest of you guys done...suggestions?

I took out the clamp, but used the plastic washer and screw that held the clamp on to fill the holes. It's not the most elegant of solutions, but it fills the holes for now.
