With the heater area fully sealed inside and out, it should last the life of the car now, I also modify the bubble a little so the water actually does flow out instead of having the water held back by the factory hole. Mine looks a little dog kennel shape but it works !

Bubble back on for fitting alignment as close to factory as possible, as for sealing the welded seams I get 2pk paint and drip it down from the inside top corner and let it seep down till it's all the way out, I do this a couple of times and then spray paint in behind the area as best I can, I usually paint the inside before the bubble goes back on.

After that bit of fun I moved on to the drivers kick panel, I found a set on eBay UK for £30 , they are galvd which was slightly annoying, only needed to linnish where welds will be going so they will prolly out last the car !

Here's the old panel removed and compared, the indents are slightly different but it's fine
