Some advice please

[Ippypicasso]

Hi
Purchased a late 52 plate 2.0 Picasso HDI in January, and had it's first MOT today.
It passed with flying colours except for a small patch of welding required under the front passenger side sill, £40, so no real complaints. Guy at the garage said that this is fairly common on Picasso's, and so I would like to know what can be done to prevent further corrosion in the future. Reading through various internet forums I see that it is indeed a common problem, and can be caused by water getting trapped inside the sill ? Apparently there are drainage holes somewhere ? How does this water get inside the sill (excuse my total lack of knowledge here).
Apart from this small issue I'm really pleased with the car, extremely reliable and economic.
Thanks in advance for any advice
Paul

i have just last week fitted a new sill to my friends picasso,

i found the drain holes were completely blocked with the under body rubberised coating from the factory,

it is normal for water to get into a door sill but its meant to be able to run back out

i think it was this company we bought the sill from,
