Default Thixotropy of body filler vs. that of Sikaflex.

I wonder if the Non-Newtonian fluid mechanics experts out there can help me out here.

I’m getting close to gluing the body on for the GTO and I’ve spoken to the folks at Sikaflex who recommended 252 elastic adhesive. That’s okay for the gluing but I also need to bog (bondo) across the join of the fibreglass and metal skin on the roof.

I can foresee cracking if the set Sikaflex moves at a different rate to the set body filler – 240Z weren’t designed for 350hp.

Is anyone aware of particularly ‘high flex’ body filler? Thanks.
