Burn marks on clothes

Opened the top of the dryer (no tools needed).
used socket set and removed the two screws (one on each side). unpluged wires from front panel, labled each (good practice).
Pulled open the front panel.
cleaned old felt off all around the front panel. Wiped down everything. while I had it opened, I vaccumed out the dryer underneath.
used glue provided in felt kit and glued new felt where old was.
let dry, put front panel back on ensuring that the felt was between drum and front panel.
put screws back in front panel. closed top.
Let me say that this is the third time I've done this to this dryer as it is about 18 years old.
Until the heating coils go out, this is the cheapest fix there is. :-)
