Just used the stuff Martin trim sent, I figured its best to listen to what they say and follow their advice. I asked them to send me everything I'd need to do the job.
I spent quite a bit of time watching on line videos of pros doing the job, watching for little tricks and techniques. The clean sponge really helped getting the fabric into the contours for example. Once the glue is on, there's no going back. Also you tear the foam from the back if you try and lift the fabric once it has touched the surface of the liner, so its a once started go until you finish job. You have to picture in your mind and have a plan in place as to which way round to work.
I'm in no way affiliated with them, but they really were helpful. They stopped me from choosing the wrong fabric, I'd chosen from some samples they sent, but when I went to order they said that colour I'd selected was not used on my model, although it looked a good enough match to me! They sent me the correct colour, so used their experience to help a customer with no experience.
