Filling gaps

[DHTech]

Would you guys recommending filling the area where the MDF butts up, the MDF edge is butted at a slight angle and you get that sort of V grove, is this worth filling? The MDF is tight against each other a you can just about see a thin sliver of light.

Any recommendation would be good, Thanks, Jeremy

Cut your wood at an angle so that there is no gap.

If it doesn't need to come apart again and you don't feel like redoing it just fill it with bondo.

if you already put them together and its too late to pull them apart to angle cut, just bondo it.
you can even first round the sharp edge with a sander for a smooth rounded edge.

And if you don't want to buy BONDO just collect some of that sawdust (should be plenty of it  ) from the cutting and mix it in some wood glue and use that to fill in the gap and sand as needed once it dries.
