I've posted this before but if you haven't replaced the rubber gaskets or injected something into the separations at the mitres, try this. Take some butyl putty (mine was just trimmings from rebedding a fridge vent), Stuff the stuff right in the gaps at the mitres. You may want to take a q-tip and some Windex and clean those gaps of dust and grit to assure some adhesion before "stuffing". Keep pressing until it more or less conforms to the shape of the gaskets. Take a black MagicMarker and "paint" it to match the gasket. I think you have already cleaned the freeing ports in the sliding window channel. In a heavy rain, sheets of water on the glass will not be able to run thru those separations wholesale and the freeing ports will be able to keep up. I know this isn't very elegant but sometimes interim solutions can function for a very long interim. I think you will find that the replacement gasket will, in time, shrink just as much as the one replaced so this fix is worth some thought.

You are recommending butyl tape between the glass and the frame when a window breaks and you simply replace the pane of glass?

No, between the window and the trailer. Sorry if I didn't make that clear. Raz

Laura, if you think it's leaking in the areas where the window glaze bead has shrunk, your choices are either to replace the bead or fill those areas. If you're looking to fill the cracks, maybe use this... and yes, I know it's silicone, but you're not putting on the body: Loctite 37460 3 oz Black RTV Silicone I used it to fill the gap in the gasket and lockstrip on my Scamp.

Or if you want to change the bead, maybe check here at the bottom of the page: Interstate RV Metal & Supply
