So, it doesn't look like much, but this is several hours work!
The kit came with a resin cast of the rear spoiler, but one of the brackets was misformed, the other wasn't very robust, and in the wrong place. also, the edges had cast voids, so I've out out some styrene and glued in place, needs to be filled & sanded smooth, and i've scratch-built some brackets, they are way too thick for the scale, but I can't make anything smaller, and i want it to actually hold the wing!
I've decided not to re-add the front grille of the car, it's going to match the re-build of the car as per photos I have rather than the Longhust version as raced.
