Teardrops n Tiny Travel Trailers

I am building a painted camper. (exterior house paint on plywood) I would like to install aluminum trim around the edges after the paint has been applied to the camper. I am still undecide if I want to use Edge molding w/ an insert or just plain aluminum angle.

Is there any special steps I should take to keep water from getting under the trim?

Should I worry about water getting into the screw holes?

I used polyurethene caulk under all of my trim pieces. You could probably use silicone also, but I have not used it myself. I would say that you should always put some kind of sealant in any screw holes that you make!!

Weeeeell here in Scandinavia the moulding I use does have a formed rubber seal and under it lies a butyl tape all in one... that is shaped to my trim or moulding.. here the 2 types Ive got.







How,s that for being different.. Im laughing now but sure wasnt when hunting for the moulding or trim..

I used plumbers putty tape. My trailers been in some pretty nasty downpours this past summer and not a leak to be found.

3M 5200 we use it to seal parts on the bottem and top of boats it does not leak you can get it at boat stores or home depot

Will the polyurethene caulk creat a good seal between painted wood and aluminum?


Should I place a dab of it in the predrilled holes before I put the screws in?



Thanks everyone for your help. I have a long way to go.

Yes it should do a fine job.

Yes, I would advise that you do.
