This is how I was able to carry some plywood ! Yes ! Important points and precautions are ;
1) First place plywood on the car, then just tie them at the back firmly (without ratchets because at angle, ratchet doesn’t work properly). Once tied, pull plywood back to achieve maximum stability.
2) plywood needs to be aligned with roof of the car and excess length needs to be more on the back than front of the car.
3) plywood needs to be tied at least at 3 POINTS, if you do 1 or 2 only it might slide and cause problem.
4) They need to be TIGHT, yes almost really tight to achieve maximum grabbing and prevent it moving. (BEST WORKS WITH TIE DOWN RATCHETS).
And there ya go!
