| + | As mentioned before, this shroud is going to need to enclose the radiator where the fan swings 1" above the top. This will require a seconary lamination to form a return. | ||

| + | As the return can be flat, and on the same plane as the mounting surface, a table top will be used for the mold. I simply tape the top off with some masking tape, then wax the tape with some mold release wax. I like Partall#2, AKA "green wax". | ||

| − | [[Image:59lay up the return.JPG|center|600px]] | + | I just clamped the shroud to the table, then laid up 3 layers of mat. |

| + | Once the laminate has cured, the part can be removed from the table. | ||

| + | I use polyester surfacing primer on all of my plugs and one offs. Evercoat-Fiberglass Co. makes a material called "Featherfill", Poly Lux Inc makes a polyester surfacing primer, and Hawkeye industries has a line of Primers that are well suited to filling all of the pores and sandscratch marks left by shaping. | ||
| + | |||
| + | I like the Duratec surfacing primer the best, you can build up to .040" in a single application. | ||

| + | As you can see, this is a high solids primer. | ||

| + | Nothing fancy in the way of spray guns here, this one is a very old Devilbiss that I bought at a garage sale for $1.00. | ||

| + | Now that this part is primed with the polyester coating, it can be sanded and top coated with whichever paint system you like. Also, if I was going to make several of these parts, I could sand and polish the surface, wax it and use it to create a mold with which I could duplicate it many times over........ | ||
