I've got a vango killington 600.
I think i may have messed up the waterproofing on it ,
when ive been cleaning it i used normal spray cleaner and a sponge.
Last time we went camping it rained quite bad and in the morning there was loads of big puddles of water it looks like its dripped from the top and also looks like its leaked from underneath through the groundsheet.
Ive looked on the internet for waterproofing things and there are sprays and liquids that you paint on.
But im not sure which whould be the best ive read mixed reviews on both,and also when i do it should i do the inside and out or just the inside.
And what about the sewn in groundsheet shall i do that or just buy a sheet to fit underneath before i pitch the tent.
Thanks for any advise
