I always wanted to do a sunken U-Boat. So, got a rather small scale model and could not do it due to my disability...so, tried again and got a 1:125 scale Revell U-99 kit.
Once the kit was stripped from the sprues it was deburred and cleaned, then the fun began with doing damage/rust holes, drilling out the vent holes, inserting a pressure hull segment+pipe work through the saddle tanks.
Then it was detailed, paint, washes etc.
I have enclosed some pictures, not bad for a first attempt.
Various stages of coatings and effects.
