Best paint for the sump?
Discussion

used this on numerous other parts too (un primed) but most engine enamels are a durable long lasting finish http://www.eurocarparts.com/ecp/p/car-accessories/...

looks good though Ill have you know mine is leak free at the moment 
using a gasket too only done around 2k miles though 
in saying this you can get an even more reliable seal using a proper sump sealer (no gasket material) Dirko , Reinzosil etc application method is critical however 
It's funny how these things go but, my experience, give Dirko the widest berth possible... (regardless of paint and full marks to those who can be arsed).
Definitely do not use the 'rubber' ones that are out there; unless something has changed, they are made from EDPM, which is not oil resistant and certainly not hot oil resistant. Mine went hard and crumbled in very short time - junk, and expensive junk at that.
Have tried the nitrile foam thing a couple of times and although initially promising, that broke down too. Pains me to say it as it's soooo old skool but dense cork with Welseal is the most effective (degrease and thread seal the fasteners and use little o rings under the washers too).
Will still seep

Fiat are experts at making sumps that rust from both inside and outside at the same time, i.e. Fiat Punto is the best at this
But, Fiat, IMO, make the best sump sealant of all. Since I last fitted the sump with a nice thin line of the black goo there is till no sign of a leak
.............but
I now have a small leak from the sump plug and have tried genuine and various other types of washers (bonded, copper crushable, aloominum)
Thinking the weld may be cracked.....

My son's Punto needed a new sump, but I suspect that was more to do with stone chips at the front really....But, Fiat, IMO, make the best sump sealant of all. Since I last fitted the sump with a nice thin line of the black goo there is till no sign of a leak

Thinking the weld may be cracked.....Why don't they make them of Rubber or heavy grade plastic?

I did mine at the start of the year just using some high temp rtv sealant as expertly demonstrated here by Xworks.
Coming to the end of the summer and the garage floor is still drip free.
Best i`ve done to date.
Not used it on my RV8 Rich (still on cork) but Carsy's pics are spot on a 5mm bead approx Coming to the end of the summer and the garage floor is still drip free.
