Remember to leave a little and then just use a sander to work out that last little bit - we used an angle grinder with a sanding disk to make small "adjustments" until everything was tight.
If you plan to add carpet you can hide any "misses" with that - you can also add an aluminum carpet trim piece to cover any gaps
