Hey all,

Thought I'd post up one of the projects I'm working on at the moment; moulding a replica Nissan Skyline R34 GTR rear wing. I have just completed the moulds for the wing stands, and a couple of reasons I wanted to post this one up was firstly because it was actually a more complex shape than it first appears, with several sneaky undercuts. And secondly, I wanted to show the way I prep my plugs.

I do not like using 2k paints, I refuse to use them myself. Instead, I spray my plugs with ordinary single pack high build primer, which I then flat down with 400 grit and go through the grades to 2000 grit before polishing up, as per normal. The high build doesn't polish up to a nice gloss very well, but I do it for the sake of surface porosity. I then spray the plugs with PVA (no wax), spraying it as I would a paint, although the PVA is actually more forgiving. This gives me a very nice, smooth, glossy surface. I know a lot of people recommend using 2k paints, and a lot of people don't like PVA. And while I see the benefits of 2k paints etc. for me, the single pack high build is a hell of a lot cheaper, a hell of a lot easier to use, and a hell of a lot safer. Then the PVA gives me very close to a perfect surface finish, and only requires a quick flat back and polish up which I do on all my moulds anyway.

Will post up pictures once I have infused a part.

Looking good. (not seeing the "sneaky undercuts" in the pictures thoughWink)

I understand your concerns over 2k paints but please don't underestimate the health concerns even with 1k products. Anything airborne even PVA creates an increased health risk. I prefer to use full PPE  and feel confident spraying 2k products than the very common practice of "well its only 1k it will be fine" point of view.

Oh yes don't get me wrong, I wear my PPE when spraying single pack paints, but the required PPE is actually affordable for what could still really be considered a hobby for me. The equipment needed to spray 2k paints safely just isn't viable at at the level I'm at, and I wanted to show others at a similar level that it's possible to achieve close to perfect results using PVA. I also work out of home and live in a relatively dense town site, so my neighbours are right on my my fence line, meaning I watch out for the chemicals I'm sending their way too. One day when I'm making 80k a year profits and have my own workshop, then I'll consider getting set up to spray 2k's.

Health issues aside, I still don't like 2k paints simply because of the work they require. I HATE cleaning my guns. It's so damn frustrating when it takes 2 minutes to spray the part and an hour to clean the damn gun. I know single pack and 2k paints both require cleaning, but it's a hell of a lot easier to clean up 1k paints. 

I will get some photos of the undercuts. They weren't so bad, but I got a bit lucky with the front and back edges. The shape of them means they only slide out on one angle, and were close to being locked in.

I would like to see how you bond the two halves of each wing stand together in the final product. This will help with my current manifold project.

Thanks for sharing!

Pretty simple really, I use the excess flange fabric as a guide. Instead of just trimming it up, I use a planer to remove material along the edge until it wears through and the excess breaks away. This is then very close to to the exact shape of the mould, and I bond the pieces together with Araldite 2014.
