There is something else you should do - when you get underneath and the bolts look like they only take a 6mm hex socket to undo, its lies, my bolts were absoluteley caked in oil and I didnt see that you can get a 10mm socket around the outside of the bolt :embarassed:
Also when you are refitting the bolts, I would order a few new ones because you will be very surprised when you come to fit 2 or 3 of them that they can get 'lost' in the casting very easily (like hollow sections that dont go anywhere) and I was damned if I was taking the other bolts out to get it , only to do it all again 
You should not be losing bolts in 'hollow sections'! Some of which have access to your flywheel, not the best place to lose a bolt. I have removed my sump and many others never had to order 'spares'. If you dropped a bolt somewhere then undo them all and drop the sump again to retrieve the lost bolt - simples.
None of them go anywhere near the flywheel, the next time I have one off I will show you, its where the casing is thicker (gearbox side) I had already attached the sump and was on the last 1/2 bolts and trust me they can go to where your fingers cant reach
I have taken my sump enough times believe me. Theres 2 that most people can't get to very easily and many drop these bolts, you can put your finger in there and feel your flywheel, next time your under the car put a fibre optic camera in and have a look for yourself please but do not state false information here. What's more if I drop a bolt I would not leave it in there, I would unbolt the sump and retrieve this bolt, I appreciate you may have a different approach...
There are gaskets for the sump, it is designed to be used dry and so there's no waiting time for the sealant to go off before filling the oil, it's also re-useable, which can be convenient if you will be taking your sump off now and then. Here's a picture of mine:

Personally I would only get the gasket over the sealant if you know you will be taking the sump off now and then, the gasket isn't cheap and the sealant works fine.
