Can I assume that grease trapped in super small scratches in the port seat will carry the load of the acrylic. These are swirls left after sanding and polishing the seat. How much grease do I actually put on the seat? When I grease the seat with a very thin layer, air gets trapped in small bubbles even when I rotate the port. I have seen these marks in the grease in pictures of other subs with conical ports. Are those air bubbles a problem or will they squeeze out under pressure?</div><div dir="ltr">Thanks' Sean</div><span class="yiv5805489101HOEnZb"><font color="#888888"></font></span><div dir="ltr">Hank</div></div></div></div><br clear="none">_______________________________________________<br clear="none">
