RE: is there a difference between irons?
I have the [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXB361&P=ML]Coverite 21st Century Sealing Iron[/link] and love the temperature adjustment. I bought the matching trim iron and was disappointed with it's performance. I use a [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXHZ28&P=ML]Top Flite Trim Seal Tool[/link] for detail work.
