Toni Gomes was also on the mark as the young Reds played their first game of 2017, while Sheyi Ojo enjoyed a 45 minute outing as he continues to sharpen his fitness.
The Reds opened the scoring on 14 minutes when Wilson netted after a pass from Paulo Alves and Gomes made it 2-0 after being set up by Matty Virtue.
Dunn then came off the bench to make it 3-0 and Wilson got his second when he followed up to net after his initial penalty was saved.
Dunn, who had a loan spell with Morecambe at the start of the 2016-17 season, then completed his hat-trick with two fine efforts.
