Managed to get the first two layers of fiberglass done last night, but had to stop because TechShop was closing for the night. Went back for a few hours today and got 2 more layers added on, for a total of 4. Im honestly considering doing a 5th and even 6th layer when I get back in the shop next. XD I want this mold to be very, very sturdy.

The first two layers I just used the resin on its own.

Then for the 3rd I added black pigment, and then yellow pigment for the 4th layer. This is just to make it easier to distinguish the layers and see any spots I may have missed.

Got the final 2 layers of fiberglass on the Fender mold. I realize the top layers are pretty ugly and have a lot of bumps, but I believe the inner layers, and more importantly, the layer contacting the gel coat, are all nice and smooth. The last layer or 2 was just kind of a rush job due to time limitations that day.

Next up is starting on the polishing and waxing of the skirt, then release agent, gelcoat, and onto fiberglassing the skirt!

More progress!

Took some 1/2" MDF and cut it to fit around the edge of the skirt to make a pair of 'fins' that will let me make the 2-piece mold. Clamped them on with some bar clamps, and got to work waxing, waxing, and waxing some more. Got 5 coats of polishing wax and 6 coats of release wax put on before moving onto the PVA release agent. The release agent was applied with a cup sprayer, and I put it on a little thicker than I did with the fender.

In between coats of wax, I also managed to remove the fender plug from the mold! It took some doing, but the mold came out great, and the plug is almost entirely intact. After removing the plug, I went to clean the film created by the release agent, and while it peeled off nice and clean in some places, it took some scrubbing and buffing in other places. Thats why I applied the release agent thicker on the skirt; I figure if its a nice, thick, solid coat, itll be more likely to stay in one piece and peel off, rather than just tearing every time I try to peel it. Hopefully the skirt mold wont require as much scrubbing when its done.

As you can see, the plug did suffer SOME damage while being removed from the mold, but all in all Id say its still in great shape. Will a little cleanup and a little repair, Ill have a nice spare fender lying around in case Conrad's ever breaks.

Ive got some things to take care of Monday and Tuesday, but Wednesday I should be back in the shop and getting the gelcoat and fiberglass on the skirt, as well as starting to prep the fender mold for making the final product. Cheers!

Havent had a chance to update recently, but I managed to get the gelcoat applied to the front half of the skirt, and then applied a couple layers of fiberglass before the shop closed. Went back a few days ago and got another 3 layers added, for a total of 5. Debating on whether I should add a 6th layer, or just move on to starting the other half of the mold.

After finishing the front half of the skirt, I realized that a ton of resin, gelcoat, and release agent had all dripped down onto the back half, leaving the top and bottom back half of the skirt looking like someone had dripped multi color candle wax all over them! I didnt get any pictures of it because I was so annoyed, but you can sort of see the drips in the first picture of my last post.
It was a huge pain, but I managed to get it all scraped off without any damage to the skirt beyond a few scratches, which I then remedied with an orbital palm sander. Here's what it looked like all nice and cleaned up. I also removed the two 'fins' that I fitted to the skirt so to make a seam for the 2-piece mold. Im pretty pleased with how the fiberglass underneath came out so far.

After this, it was a few coats of polishing wax, and then on to the release wax. After that, a nice thick coat of PVA release agent.

Once that dried, I applied the gelcoat. I wasnt able to get any fiberglass onto this half just yet, as the gelcoat was still far too wet (not just tacky, but still fully liquid in some places) and the shop was going to be closing soon. Im going to be heading back to the shop as soon as it opens tomorrow morning so I can get at least a couple layers of fiberglass on there. That way, even if someone bumps it or some such, it wont damage the gelcoat.

I also managed to get the fender mold finished up. It had a few little pits and divots here and there that needed filling, and the whole thing got a good sanding to make sure it was nice and smooth. There was also the raw fiberglass on the inside of the hole that wasnt covered by gelcoat, which I trimmed off with a jigsaw using a special blade made for cutting fiberglass. (but not before completely burning the teeth off of a normal jigsaw blade because I didnt want to have to stop and make a trip to the sttore) The fender mold is basically all set to cast the actual fender. I probably wont have a chance to get to it till next week (I wanna get the skirt mold dont first. I dont like having the raw gelcoat exposed like that since it could get damaged while its not protected by the fiberglass) but once the skirt mold is dont, Ill be all set to apply the release wax and release agent to the fender mold, and then onwards to more fiberglassing! :)

Back from the shop, and I managed to get 3 layers of fiberglass on the fender, and one last layer on the second half of the skirt mold. Next time I head to the shop I should be able to de-mold the fender and see how the final product turned out, as well as removing the plug from the skirt mold and getting the mold ready for making the final skirt piece.
