    Engine blanket ftw.

    Don't let dealers know about it or they'll make it some crazy expensive dealer add-on item at purchase.

    I think your suggestion & Mitz's seal strip suggestions are great!

    I swung by the local home improvement store the other day and picked up some of this stuff. It is 5/16" thick.

    I then checked out the car, and stuck it to the front edge of the hood.

    This did virtually nothing to close the gap. I unfortunately installed the weather stripping in an area that was a bit recessed. It looks good, but it doesn't help. Also, 5/16" is not NEARLY thick enough to close up that gap. I should have measured before I just went out and bought something. Oh well. This was the thickest stuff they had at the store too. I guess I'll have to order something online.

    I did learn that a 5ft length is just about perfect.

    No .. it can be removed if you are careful enough. It's only put by the dealership upon PMS schedule to discourage messing with the radiator IMO.

    Alright, I found out the hard way that the 5/16" stuff isn't nearly enough. So, what is a guy to do? Measure it of course! So, I measured my gaps the other day with a piece of dough. Yes, dough. I made up a piece (flour and water), and put it in the hood opening to get smashed like a home made piece of plastigauge. Then I let it freeze. This is what resulted. The narrowest area is 3/4" thick. So, I need a gasket seal that is at the very least 3/4" thick. Ideally, I'd like thicker so it actually deforms and seals a little better.

    Who knew cooking could be so much fun!









    The bulge in the middle top is from the piece of weather stripping I already stuffed in there. So, I'm going to take it out as its doing nothing. But, I think the step up on the bottom is where I'll stick the new weather stripping. I just have to find some stuff that is 3/4" thick at least.

    With a 12.5' long strip, a person could do two Mirages for the price one!

    Or run up the sides to the cowl.

    Daox- think you could 3d print up a clip-on 'sweep' that extends the hood a little bit and lays over the bumper cover? Do you know what I mean? Just a flap that clips to the hood edge.

    It is a possibility. You'll notice they did add holes that look like they might be for clips to hold in weather stripping. However, I think a rubber type gasket is a much better solution. It will form to the contours and seal much better than a plastic strip.
