Well, my heater is blowing foam out the vents. I've seen a couple "how to" pages online to fix this problem. This one is probably the best:
http://1705.net/archives/1085. I believe the person who wrote it up is even on here. I was going to do a basic copy/paste on our van. I started by ordering up the foam from McMaster Carr but when I saw the total I hesitated. A little over $200 in FOAM!
I'm looking for a little feedback from those that have been there/done that. Some of the other write ups suggest an aluminum tape. How's that holding up? How about the originator of the 1705 post, how's that foam holding up? I don't mind paying if that's the best option. I just want to look at my options first. If there is a cheaper, quality way to do it, I'm all ears. However, I rather pay $200, than do it again next year.
