I always get my vinyl roofs from https://www.martrim.co.uk/ They can supply with or without seams and I believe they can still do the 'C' pillar trims in a similar material. |

Hi Mart, Thanks for the reply. I did ring Martrim yesterday, but they say that they now only supply the material by length and width, they no longer supply roof material trimmed to fit. I do have the old material that’s pretty much complete, but don’t know if I could cut it accurately enough myself, perhaps I will give it a go, as Martrim said they could probably match the material grain if I provide a photo. Has anyone tried this themselves? Thanks, Rob |

Rob. You just need to order a length of material. I think 2 metres is enough, but I'd have to look back at my old restos to know for sure. |

Mart and Steve, Thanks to both of you for your replies, I will buy the material and give it a go myself. I can get one of my sons to help. The satisfaction of having done it yourself is still very pleasant. If I screw up, I’ll have another go |

Another tip or two, to spread the glue, it's very important to a) not put too much on that it forms lumps under the vinyl, b) get a good, thin-but-even coverage on both roof and vinyl, c) wait till the glue is ALMOST dry before mating the two together and d) apply the vinyl initially along the roof centre line and stretch it carefully out, working out towards the sides to eliminate any air bubbles. Cliff favours a home made glue spreader made from scraps of millboard, but you can buy plastic filler spreaders from a paint supply shop like Jawel Paints for not much money that work as well. I guess when you do as many as Cliff does, the cost would mount up quickly! Be prepared to junk them when you are finished! When applying the glue in tight spots like the guttering, a 1" paint brush is useful, this will also be junk when you're done so don't bother with a good quality or expensive one! A 1 litre pot of glue will be ample, Martrim will sell you one with the material. Or Cliff recommends Wayside Adhesives high temp contact adhesive HTA1000. I've used both and, frankly, I can't tell the difference, but Cliff swears by the stuff and he should know! Finally, a drop of panel wipe (also from Jawel) is good for cleaning up stray glue when you've done and doesn't hurt paint. It's also great for dealing with excess screen sealer when you've put the windscreens back in! Steve |

I've always used spray contact adhesive on the vinyl roofs I've fitted, so no lumps & no spreading. Martrim can supply. You definitely need to stretch the material as you go, not excessively though. |

I guess i'm old school! When I worked at Car Hood Company back in the 70s, we always used tins of glue rather than aerosols, probably, as with Cliff and the spreaders, for cost reasons more than anything else! A litre pot is cheaper by far than the equivalent in aerosol form. When you are using several litre pots per DAY, as we were back then, this would be a factor! Not so much for a guy doing a single vinyl roof for his own benefit!As i've never used aerosols in this way, I can't say for sure, but I imagine spraying it on the roof would be a bit problematic with glue overspray going everywhere you DON'T want it and giving you a sticky cleanup problem. Or time and materials to mask it up. But it's only a guess! Steve |

I don't think the spray-on contact adhesives are as strong as the pot stuff. I fitted a headlining with a spray can adhesive. During hot summer weather it came unstuck and drooped down. Repeated with a pot of Alpha contact adhesive and it's remained good for 10 years so far. |

Thanks everyone for all your advice, I have bought a trimmed version of the material from Aldridge, and I'm now preparing my roof, getting the old glue off is pretty time consuming, I'm using a stanley knife blade with petrol, slow work, but I'm getting there. I've got a small patch to weld and fill around the drivers A post, and numerous rusty patches to treat and fill. I've also had to weld the gutter at the rear, and around the top edge by the screen, which is a bit awkward, as it is right on the curve. Further welding also needed at both bottom corners of the screen too; it's always leaked on the passenger side, so this should now cure that at last I think that I will use the glue from a pot, at least it is controllable and you know where you are putting it. I watched a video showing the roof glued starting from the centre and it looked like a good way to do it. I'll post some further pics next week. |

I used a toffee wheel to get the glue off. Had it done in no time. |

AKA "caramel wheel" I second this, these things are brilliant and not expensive. Got mine from ebay for less than a tenner including postage. Panel wipe also shifts glue pretty efficiently. Steve |

Update. After welding, filling, sanding and painting my roof over the winter, I've been waiting for a nice enough day when I'm off to fit my new vinyl roof. Today was the day, and I've completed the job to my great satisfaction. It's one of the more stress inducing jobs that I've done, probably because it's my first one. "Have I got enough glue?" Yes, but only just. "can I get that crease/bubble out?" Yes, but only with some stretching and pulling, sometimes I could have done with an extra hand! Next job is getting the front screen back in, but I think that I've had enough stress for one day.
