Stackable automotive water shields including a channel with inwardly angled walls containing an adhesive

A stack of water shields without release sheets therebetween, comprising:

• a bottom water shield including a water resistant material shaped to include a bottom channel with inwardly angled walls and a bottom base spanning vertexes of the angled walls and a bottom opening opposite the base such that Θ′ between a first wall and the bottom base is between about 40 degrees and about 75 degrees and Θ″ between a second wall and the bottom base is between about 40 degrees and about 75 degrees;
• hot melt adhesive in the bottom channel;
• a second water shield having a bottom surface in direct contact with a top surface of a bottom water shield, the second water shield including a water resistant material shaped to include a second channel with inwardly angled walls and a second base spanning vertexes of the angled walls and an opening opposite the second base;
• hot melt adhesive in the second channel;
• and
• the second base being over the bottom opening such that the angled walls in the bottom water shield shape the bottom channel to create a vertical clearance over the hot melt adhesive in the bottom channel sufficient to prevent the adhesive from contacting the bottom surface of the second water shield in the stack, thereby eliminating a need for a release sheet between water shields.
