Having just built a new sub box, i am not done finishing it totally. I would like to do a 1/4-1/2 fillet on the edges to round them over. However, i used 2in drywall screws in building this so i didn't have to drag the build out with clamping all the time. I used pl premium and the wood is the EFS mdf looking stuff.
Would i be able to pull the screws and plug the holes with filler so i would be able to router the edges? And still maintain structural integrity?
