Hi Chris,

Sounds like we've made all the same observations about fluid film. It did mess up the front hood seal on my 745NA and the door handle seals do stick out a bit, although they were like that when I bought it I think. The previous owner had it rust checked a few times. I haven't had a problem with a taillight seal yet though. Also, as you said, it's not the best for exposed floor pans and places like that. Underneath I only use it inside closed frame rails and body sections or in areas that aren't directly exposed to strong water spray. Certainly don't want to waist the stuff considering what it costs!

Do you think something like rockergard/rubberized undercoating is the best to use for the uncoated, exposed underbody areas and things like the k-frame? POR-15 makes this: http://www.stright-mackay.com/asp/details.asp?HeadingID=2072&CategoryID=11 ,but it says to apply it over regular POR-15. Doesn't say anything about areas that are not treated with regular POR-15 and it's pretty expensive. I figure $30-$40 worth of rockergard/rubberized undercoating would do the trick instead...
