candle wax

couldnt resist mate 
lol, i wondered when that was coming

for the record, i didnt try it, was an idea off vw vortex,
ive decided as the one i got out the spark plugs looks ok, im not gonna mess about with em for a bit, ive tried everything i been told, and they aint budging, i think it will be a case of of go for it one day and have helicoils at the ready, cos its my daily i cant mess it up, but when the time comes, they will come out (hopefully) one way or another.
my local garage says they would try but if snapped it will be 50 per plug and someone comes out and does it for them.. wish i knew who it was..
