Installing Rear Main Seal - BBC

putting my motor together. Checked bearing clearances, oiled the bearings, etc. Ready to put on the last main bearing cap and rear main seal and start torquing everything down.

Question: Should I use some RTV around the rear main seal and rear main cap area? Just a very thin film perhaps. Or am I safer and better off using nothing except the rear seal itself? I have a Gen IV block, 454 and it has a 2-piece rear seal. I have 2-bolt main caps.

For some reason I don't trust the rear seal, even though it's new, to completely seal 100% back there. I hate oil leaks.
