Wilders, surrounded by bodyguards and police, visited a market today in the largely blue-collar town of Spijkenisse to hand out the sprays, which contained red paint.
Amid stalls selling vegetables, fish, flowers and bicycle parts, Wilders got a rock-star welcome from dozens of supporters, while others protested his visit, waving placards including one that read, "Refugees are welcome, racism is not."
In between shaking hands and posing for selfies with supporters, the Freedom Party leader said that, if elected, he would, "close the borders immediately and have no more asylum-seekers. We just cannot afford to have more. The Dutch people in a big majority don't want it and we cannot afford it and it makes our people and women only more unsafe."
His message is gaining traction here amid a surge of refugees to Europe and following deadly attacks by Islamic extremists in Paris last year.

"The tendencies across Europe are very similar," said University of Amsterdam political science professor Wouter van der Brug.
"Across Europe, right-wing populist parties are picking up support as a result of the asylum crisis that we're facing now, and also as a result of terrorist attacks."
Leontine Maris was one of the first women to get a spray from Wilders. The 53-year-old said she votes for him though she disagrees with some of his more extreme comments. She said she was afraid not just of migrants, but also Dutch men.
"Wilders is getting support across different layers of society," Van der Brug said.
