plastic door liner

[attwood]

Can anyone tell me how the plastic sheet inside the doors should be fitted?

From examination of the remains of the old liners I have it looks as if it should be inside the door at the top, trapped under the window frame fixings. It then goes down inside the door and is sandwiched between the door and the window regulator. At the bottom it seems to come out through the big hole and is trapped between the door and the trim panel.

Is that how it should be? Or should it be inside the door all the way down, glued to the metal work?

Thanks for any tips.

Dave.

Dave, if you mean the plastic sheet I think you mean, I used a builders plastic bag (heavy duty plastic) and stuck it to the door shell using wide, clear plastic sticky tape. It is there to protect the hardboard trim and t ensure the water is directed inside the door. Colin Ford (I understand) sticks it to the inside of the door but I have only seen it between the door trim panel and door shell.

As I understand it, water gets past the window seals, collects on the metal channel holding the bottom of the glass, and then drips down inside the door cavity. As the inner door skin is at an angle, this water can drip through some of the larger holes in the inner door skin, onto the back of the trim panel, and run down to drip onto the sill from the edge of the trim panel. The plastic is to prevent this.

The holes in the inner skin have edges which are folded back inside the door cavity. Taping plastic over the top of these holes (ie between door skin and trim) potentially creates water traps as these edges form small channels which can collect water. So I'd say ideally it would be best to put the plastic inside the door cavity. I compromised as I did not feel like taking the winder and door handle mechanisms out, by using smaller pieces of plastic over the larger holes, with their bottom edges tucked inside the door cavity to direct water back inside away from those channels. I also have door trim boards made of varnished marine plywood for increased water resistance. I guess I'll find out this summer if that has worked or not - if not, it'll be door strip down next winter.

Thanks for the tips guys.

Angus, coincidentally I was measuring up a builder's rubble bag for the purpose earlier in the evening before I read your reply!

I think I'll go for the inside of the door with the plastic held in place by the window frame and regulator. Probably just let it hang loose at the bottom. That way I can spread wax around inside the doors and not have to worry about getting the plastic to stick to the metal anywhere.

Regards,

Dave.
