Polishing Acrylic Surface Prior to Bonding

hi
I need to bond two acrylic sheets at the faces (not edges) to make a thicker piece. As the acrylic sheets were milled, the surfaces were not optically clear. Is it ok to polish (sanding/micro mesh followed by novus) the faces before solvent welding?

I understand that polishing is not recommneded for edge joining but i'm not sure if that applies for this case too. If internal stress buildup is a concern, can it be alleviated by annealing?

Thanks..
