Teardrops n Tiny Travel Trailers

As I've posted elsewhere (build thread in my signature), we are updating/modifying our home built TD.

When the builder built it, he left the wooden corners exposed. It's all sealed up, but I'm concerned with moisture getting in there and to be honest, it doesn't look that good, either. I've seen aluminum edging/molding, but am wondering if maybe there is a wood or imitation wood product that would serve both to protect the wood and to hide the ugly edges? Anybody know?

EDIT: Added a photo. See the ugly gap between the side panels and the curved top panel? That's what I'm trying to hide. Also note that the windows/portholes also have ragged edges showing and I'd like to hide those as well. Thanks in advance for any advice.

Martin, I used this foil covered sealer tape under the metal trim. It is sold in a roll about 4" wide at most home centers. It's for sealing around windows being installed in homes. It's about 10 bucks a roll. Makes a great seal. The black sticky tape also seals all screw going through it. It's cheap insurance. I used it on all my seams after finish was installed. Sorry I do not know of a trim other then the aluminum but this seal tape is worth putting under any trim. Keep in mind, the aluminum trim has an insert that covers the screws. That is another barrier to keep water from getting in around fasteners. Good luck.

Hi Woodbutcher - That's a great idea. I also like the idea of using
the similar product, Ice Shield, as an undercoating. The nail/screw
sealing feature is hard to beat.

Hi Martin - Fellow forum member linuxmanxxx [If I recall correctly]
uses flexible plastic [urethane foam based?] moldings for his trim. I
don't recall if it is interior or or exterior, specifically, but UV matters
could be handled with a UV protecting paint. I'm also assuming it is
installed with a construction adhesive or something similar. Maybe
you could find one that'd double as a sealer as well. I used some
crown molding made of urethane foam once. After filling and sanding
that down, it looked just like regular wood molding once it was painted.

Here is a thread from the TD Mfr Section for him. And also his TD
business website. You should be able to probably ferret out the
details between them - or maybe an email to him could get you the
info.

I also recall he mentioned the source he uses for the trim. That's in
one of the posts somewhere. If you use the new Google Search on the
forum, just type in "linuxmanxxx Posts", and it'll bring up 10 pages
worth, it's probably in one of them.

Another forum member - AlgoDan - has a thread in the TD Construction
Tips and Techniques section on using house PVC exterior trim pieces that
he rips down to the profile he wants: My Homemade Roof/Wall Mldg.: It
looks to be very close to what you want.
