Managed to fix a leaky airbed with some of that green gungy stuff you buy for bike tyres. Just squirted it in (not a lot just some I had left over from years gone by) and blew up the airbed and it stayed up 3 days instead of it's usual 3 minutes. Only used it to try to find where it was leaking from but as it's sealed itself it'll do as is!
Thats the problem I had. I used the gunge just to try to find the leak as its a flock type and from where the gunge landed it looks like it was the seam around the large screw cap which would have been hard to patch.
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
