Puncture Repair 'Gunge'

I've always been more than dubious about the puncture repair gunge which you can use and is increasingly supplied with new cars. In the past, I've always invested in a proper spare wheel or at least a 'space saver' one. However, my views are based on discussions I had with someone in the tyre business some time back (decades) who said he wouldn't repair a tyre which had been 'repaired' with gunge as it was all but impossible to ensure the gunge could be removed so a proper repair could be made. (I appreciate the gunge is no more than a temporary repair). However, with the passage of time, have things changed? Do people find that they must replace a tyre which they have used 'gunge' on (assuming the damage would normally be repairable). My question is more than academic- I collect a new car at the weekend and not only does it lack a spare wheel, there isn't space for one (the space is occupied by electric motors to drive the rear wheels).
