Dont get me wrong dabs and please dont think im havin a dig, im really not i appreciate your opinion. Its like anything all opinion based and all that. I feel that if i took a sealant tyre to a kwik fit or what ever they will turn round and want more for tyre removal? Plus if i use it its will be £20 odd to replace the sealer can so the tyres would be sealer can without the inconvenience of having to use the sealer. so its £20 your gonna spend what ever way you look at it. Sealer = £20 RFT = £20 - inconvenience I dont want to be havin the extra crap in my boot in the shape of a spare wheel especially as there is nowhere to put it. i have never used either and have always have had a spare but with no place to keep a spare this is where the question pops up.
