You will for the rest of your life, need declare refused visas.
The PMV application will look into the reason it was refused (I assume GTE requirement issues as per PAM 3) this will not directly impact the application.
We had 2 Visitor Visas refused for Ukrainians, the 3rd Visitor Visa was approved but we had to leave one of the kids behind in the Ukraine.
We then did a PMV application - a few months after that we again applied for all to get Visitor Visas for the remainder of the processing period. They were all granted and for longer than we requested.
