Seems like you have things in hand, I would say the adding the texture with either a thin layer of bondo could work, but it is harder to control, but it will be lighter than the epoxy putty which will really like you get a lot more control on your texturing but you will add a fair bit more weigh doing that all over the kit.
Thanks for the input, about the same lines I was thinking along. My old Slade helmet's horns were made of epoxy putty, and despite being an inch wide at the base and an inch and a half tall they were weighty. I'm going to play around with a few options before going crazy.
Woah! Glad to see you back. 8) I'll definitely be checking in to see your progress.
Thanks

! Your crusader build was always an inspiration, and when looking for reference pictures for my new modern era build I stumbled across a picture of you suited up in it so I decided crusader would be my first side project while I work on the Wren-inspired kit. I have something like project ADD and seem to run into a wall working on anything if I don't step back from it every so often and work on something else.
I got a bit of shaping done today, and realized in the process that I did my conversions wrong at Home Depot...so the bulk of the heavier armor parts are 12mm sintra and the smaller parts (knees, hands, biceps, cod piece) are 6mm, rather than the 6mm and 3mm that I thought, lol. Guess it's been a while since I worked with sintra, but all it means is that the thicker plates take a while longer to shape. They're still coming along nicely.

I had to cut the ab plates down a fair bit for them to actually fit on me without overlapping both the chest and the cod. I also replaced the center ab piece with 6mm. I decided on a bone chest plate rather than leather, as I'm going for a bit of a heavy look with this suit.




The shaping came out a little wonky on the foot armor, so I'll have to revisit it. ALL of the plates are only roughly sanded. I wanted the basic rounding of the edges done before shaping and plan on the final smoothing once all of the parts are shaped. I also deliberately put little effort into making the parts perfectly symmetrical, to aid in the look of crude bone armor.
I've run into a bit of a wall on the primary new kit, as it's still way to cold to paint here. When my velcro and strapping arrives I can at least get them ready to suit up, but in the mean time I'll be putting more work into this kit.
