It looks like both front fenders were replaced at some time in my cars life.
I can't say they did a bad job but they never replaced the seam seal. Originally was there a bead of seam seal at the bottom of this gap between the caul and fender? The 3 mm gap narrows to about 1 mm at the bottom. I am thinking I should fill that 1 mm gap. The way it is now water can drip thru in areas. I am not sure if that is a good thing or bad.

mqphoto, thanks for the photos. Best I can tell your 2nd photo shows the fender still on with seal above the horizontal seam filling what I am seeing as a possible drainage point.
My thinking is with a good rubber seal, water should never get below the seal. If it did, I wouldn't want it to stay there long. A weep hole may not be a bad idea. This would prevent water from running down the front trunk channel under the trunk seal. That is a rust area also. The draw back, that very little water that makes it past the rubber seal would go down toward the door stay hing that's basically a hole in the frame. I will do some water flow test tomorrow.

(IMG:style_emoticons/default/agree.gif) Cary and I were discussing this looking at several of the cars on the rotisseries. I believe the consensus was that there was an opening to allow water to not pool in the gap there but is something that should be cleaned out every few years to make sure they are not getting gummed up and holding water in there. When you are working this area I would recommend that you test fit the seal before going to paint to make sure your gap is correct and the depth is uniform so that they will be able to fit when it is time to put them on. I am pretty sure Cary has the photos. I will ask him. |
