Three second half goals saw the Robins finish their home campaign on a high at a sun soaked Latham Park.
Despite nothing riding on the game, Chris Hughes was keen for his side to finish strong, and after a stalemate first half they ran away with the game in the second period.
Ethan Jones struck twice to make it five goals in four starts, but was denied his hat-trick from the spot.
Then Kieran Mills-Evans, voted fans player of the season on the day powered home a late header to complete the win.
The Robins began brightly and on the front foot much like they did in the draw at Jenner Park a week ago.
Luke Boundford called Carl Jones into action with a cross come shot after five minutes, but it was the Seasiders who passed up a golden chance to snatch an early lead.
A long ball was flicked on and as the Robins defence stopped, Ben Maher ran clear but he was denied by the feet of Dave Jones when one on one with the keeper.
Zyaac Edwards had a long range effort saved, before the Robins defence was breached for a second time on the quarter hour mark.
This time a ball down the left channel was flicked on for Macauley Taylor, who ran towards goal before Ryan Sears recovered to block his shot.
It was end to end stuff in the Mid Wales sunshine, as the sides played with the shackles off.
On the 20 minute mark Craig Williams went bursting forward down the right and crossed for an unmarked Alex Fletcher, but the midfielder could only skew an effort wide from 12 yards.
Jones was the Robins man in form and he almost added to his tally soon after, but he couldn’t keep a volley down following a Williams cross.
Boundford’s afternoon was then cut short through injury, as he was replaced by Nick Rushton who returned to the squad after missing last week’s trip.
After the fast paced start the tempo of the game began to fall away towards the end of the half.
However it was the Robins still having the chances, as Ryan Sears headed over a Ryan Kershaw cross and Jay Denny volleyed wide.
Much like the first period Gareth Wilson’s men were handed a great chance to take an early lead in the second half.
Jones’ poor kick fell to Edwards who drove forward, before his shot was deflected behind for a corner.
The Robins then punished the Seasiders for their missed chances, as they took the lead just a minute later.
Fletcher found Jones on the left of the box and he cut in before firing a low shot in off the post, for his fourth goal in as many starts.
Within five minutes the visitors thought they’d levelled it, as Zebb Edwards latched onto a Ross Stephens free kick, but the linesman’s flag was raised for offside.
Rushton had a chance to double the lead, before Jones did just that on the half hour mark.
A long throw was flicked on and the ball eventually fell to the former Shrewsbury striker, who lashed home for his second of the game.
Less than five minutes later he should have been walking home with the match ball, after referee David Morgan awarded the Robins a penalty.
A Williams corner was turned in by a Prestatyn player, but the referee had already blown for a spot kick after Thomas Kemp tussled with.
Jones stepped up but the keeper Jones dived to his left and pushed it clear.
Despite the penalty miss the Robins were in control and should have extended their advantage late on.
Tom Goodwin fired wide, before Maher went close with a free kick at the other end for the Robins.
Rushton was denied a late goal with his header by the Prestatyn goalkeeper, but Mills-Evans made no mistake with his head in stoppage time.
The fans player of the season powered home a header from a Fletcher free kick to seal the win and end the home campaign on a high.
