Do you recommend any puncture preventative products?

Many vehicles are now supplied with no spare wheel and are often incapable of even carrying one. There are a number of products promoted to prevent punctures from occurring. Reviews of them are very positive, to the point of being remarkably like sales pitches. Are you aware of any independent research on these products and do you have any views on their efficacy?

None are as good as having a spare wheel. However, my own car doesn't have a spare so I carry about a couple of bottle of Holts Tyre Weld – I read a lot of positive reviews before I bought it and it has the advantage that your punctured tyre can still be repaired after use.
