Alright, so I've only hit some main problem points so far. I'm actually taking some of my other parts to a con this Saturday so I can use them to show others how to repair/upkeep armor, but because I'm wearing it tomorrow here's what I've done.
First I fixed the cracking spots. I found in the shoulders on the yoke where the cracks ended and drilled a hole through the end so it would end the crack point and prevent it from spreading. I then ordered some Devcon plastic welder as I heard that this was a little more flexible than just resin or fiberglass. So I mixed the two part Devcon and then filled the hole and the crack on both ends and after smoothed it out so it wouldn't require too much sanding after.
I let it sit a day and then sanded it down. As you see in the above picture it still has a lot of chipped paint and problems. So I sanded to 400 grit and then applied some bondo filler over the areas that were rough. I let that sit a day and then sanded to 600 grit.
I didn't get a lot of pictures sadly as I was rushing to get this ready for the con tomorrow.
After sanding I was now able to spray again with paint I originally used, then the enamel clear coat to get it back to a good looking shiny white.
Now it will cure overnight and be ready for tomorrow.
another thing you might note from this picture is I've cut out the front section of the yoke that's under the chest plate. Why? Because it wasn't allowing me to move effectively and it made getting the yoke on and off much more difficult. It's the reason so much strain went on the shoulders and led to the cracking continuously happening. Now I can actually get it on and off at an angle that doesn't stress the armor and helps me so much more.
I know a lot of vendors are building them like mine was built, but I'm going to say here that for guys like me that are more built in the shoulders, chest, and back, this is so much easier.
