To Seal Up Subframe Mount Drain Holes Or Not? And The Sills?

I've replaced both subframe areas with all new metal. the lower panel has the same rectangular drain holes as the originals. Should i seal these up with some plate and just inject a ton of por 15 and seal them up? or just por 15 the inside while leaving them open? I've also replaced both sills (rockers if your from the US) and filled them with POR 15. i have however only spot welded the bottom and not run a seam along. i was thinking of filling the edge with seam sealer or should i leave that open for drainage too? I live in the UK and its a pretty damp place :[

 

kind regards

I decided to close the bigger holes that let dirt in. For the subframe mount areas I drilled holes from inside under the seat and closed the rectangular holes below. Also sealed all the welded seams that are not watertight with seam sealer. Then I sprayed lot of cavity wax in all the boxed constructions and plugged the holes.
