So while i was filling my helmet i somehow managed to snap this piece.
i used some styrene strips and CA glue to fix it the best i could. i then used files to shape it to the correct contour for the helmet.
I thought this worked so well that i would try replace a couple of the vents in the back as i was a bit to heavy handed with my dremel and file.
this is where i ran into a lot of problems. I ended up replacing the 5 on the far right. I tried multiple methods of doing this with CA glue and zap kicking it so it would set quickly.
this didn't give enough strength to the styrene and it kept popping back out with a bit of pressure. to remedy this i used some milliput on the inside of the helmet to hold the styerene and CA glue combo in place. this fortunately has worked, but i am no happy with the state of these vents as they are wonky and i don't know how to fix it. i have tried using car filler putty and milliput but i'm still not happy.
after this point i went on to pilling any holes and gouges with putty and wet sanded and undercoated the entire helmet.
I also used some rubber spray paint and coated the inside of the helmet so it wasn't scratchy,
I went a bit to heavy with the first coat of white and i ended up with some streaking and runs, so i
I went back to the wet sanding and got rid of the imperfections from the first coat and have since applied another 2 coats. As you can see there is still some wet sanding that i will have to do again, after this i think i have another 1 or 2 to go and then i should be ready to paint the tears and traps.
If anyone can give any suggestions on how i can fix the dodgy vents (above) that would be great. i did have an idea to cut out the whole vent and 3d print a replacement, however i don't have access to a 3d printer.
I think i should rename this thread to "How to make a stormtrooper helmet and get every step wrong".
