Have you already taken it out? Because getting it out and back in required at least a little bit of twisting and bending. You'd probably end up with cracked resin/paint.

Unless there's some kind of flexible resin that I don't know about.

 

Little late but used a firm cheap scrup brush then shop vac , latex roll on probly best, I used stone finish spray top coat and it looks great in those areas

 

If you remove all of the seats or at least the rears and recline the front passengers, no bending or twisting is required. I didn't crack my fiberglass during install

 

Flexing was a concern but knew there is enough roof to slide in on an angle.
