For those that have used Rolle Pro

I have recently had the chance to use it and must say it saves time if the install allows its proper use. However, I did notice that with that there's always a small amount of material that doesn't quite conform to the rivet. I've had to heat and go over with my finger in order to get it to conform all the way and have no air pockets.

Is this with my application? Is it the norm? Is my rolle pro too old and softened?

I tried going to a local mom and pop hardware store and only found some very soft foam rollers to try as replacement. Didn't buy them becuase I didn't feel they would work being softer than the rolle pro.

So, what do you guys think? Do I need to improve my torch handling, get a new rolle or get a hard foam roller if there is one?
