Or the preservation of a canvas tilt When driving along in your land rover feeling everything is right with the world and god is in his heaven, have you ever had that sudden cold shiver run down your neck?, and I don't mean the one about realising its the better half's birthday, I'm talking about the one caused by a drop of rain water leaking though the canvas, if so read on and this might inspire and aid you to remedy it. The tilt on my land rover has done sterling service over the years but the last winter has taken its toll, this is no pampered restoration sitting a a large garage but on the kerb 24/7 come rain or shine and said drip caused me to take a closer look at the tilt. Not very close inspection revealed quite a few holes, mildew and general wear and tear. Closer inspection revealed a situation that needed sorting while the weather was good and excluded the cost of a new tilt. To be honest some of the materials used I already had in my shed the only real outlay is in the recolouring dye, the other items used were as follows Fabric cleaner and canvas proofer from Storm, others are available but I've heard that the cheap option of using Thompson brick sealer is not such a good idea as the recipe has been changed, Renovo soft top reviver and window polish, Copydex and some off cuts of canvas kindly supplied, for a small donation, by John Clarke of Exmoor Trim.

[IMG] (HTM) http://i791.photobucket.com/albums/yy193/roverman40/38c8025042d8ff2f6dff5015222c0cd0.jpg[/img] The hood was wetted with a hose and the cleaner mixed into a bucket of water and sponged on, I then set to with a scrubbing brush to shift the stubborn dirt and algae. Rinsing off with a hose after showed how much muck had come off by leaving a green Land Rover out line on the drive after I had finished and a considerably cleaner but streaky tilt. A second going over with the cleaner help even the streaks out and shift the last of the grime.

After digging around I the back of the shed I came up with the bottle and set to work on the window. It's easy to use and works like a metal polish, which I suppose it is, just a bit finer, pour onto a rag, rub onto the window and buff off with a clean cloth and repeat till you are satisfied.

The off cuts of new canvas were cut into appropriate sized patches and covered with copydex and placed over the holes in the canvas, I have toyed with the ideal of sewing as well but the number of patches has put me off. If they start to peel I might rethink and sew them after all. The dark spots are from either the mildew or oil I can't make my mind up. The idea of this was to make sound rather than pretty and if I can get a few more years out of this tilt, that will do me.

I have dyed large bits of canvas before in a cleaned out bin but the finish had a more camo feeling and took a lot of rinsing before the dye stopped running. Renovo to the rescue, this is the only recolouring product I could find, it's brushed on and when dry colour fast. The only thing is the limited colour available, dark blue, dark red, dark brown, black and of course dark green. The green is no where near the karki of the original finish and I did toy with the idea of the brown. On the back of the rear side flap I tried a test patch to see the effect, it goes on well and gives an even finish, it comes in 1/2 and 1Ltr bottles, 1Ltr is supposed to cover "a large roof", what ever that means, so I purchased 2Ltrs. The 2ltrs was more than enough to cover the canvas with the recommended two coats, the application was fairly easy and I would say doing it on the vehicle could end up with plenty of the dye on the ground as it's very thin and watery, Renovo do have video clips to show how to apply on their web site and I used a 2" brush but feel a larger one may have made the job quicker. After the first coat the colour was still a bit streaky and the dark spots still showed though, the second coat has evened the finish out and I'm happy with the result. I do wonder how it would have gone on if a spray set was used. The tilt it's self does not appeared to have shrunk any but it is a lot stiffer and rougher but I expect it will soften up as it flexes.

Now the not so good news, the canvas proofer that I planed to use has not taken to the tilt, in that it has just beaded on the surface and run off. Now I'm not sure if this is a product compatibility issue or the storm canvas proofer has gone off, I bought this four years or more ago and it has been stored in a shed (hot in summer, freezing in winter) and it looks like it might of separated out, it looked curdled, a bit like milk, it did improve after a vigorous shaking but still had a few lumps in. The only waterproofer I was able to get locally was fabsil, this has gone on very well, soaking into the canvas and not reacting to the renovo dye at all. The fabsil smelt very strongly of the silicone that it is based on and the instructions recommend up to six hours drying before exposure to dampness. I used two litres and starting with the top section and applying the fabsil so that it wetted out the canvas and applying slightly less on the sides, I only just had enough to finish the job off.
