Here is a picture of a plug with gel coat on it.  What would be your recomendations for infusing this. Keep in mind once this is a mold it will be basically a U-shaped mold. The kick out you can see in the picture is not on the other side. the other side is smooth.  The lowered sections in front and back (left to right) are flange area. The part area is 32" (813mm)long. The max height is 16"(406mm) and the max width is 16"(406mm).

 I really only see two options....

1. Infuse from the side and let the resin go out along the flange in the spiral then go down one side of the U and back up the other side of the U....

2. Infuse from the end and have the resin as it enters have to climb up the walls of the U in the spiral then across the part.....

Any sugestions would be greatly appreciated. Please be specific as to where I should run the spiral.
