i got a crack of abt 4 inches in ma crolla windscreen... n it increased to 7-8 inches within 3 dayz.... in Multan there is a person who fix it by using elfy type chemical in rs.400.... 30% crack was removd but the existing crak didnt grow even a single cm after that treatment n never leaked...
in isb there must b some person doing this... but need to find them out, coz these ppl dnt hav shopes... they just pick up a bag n wander around the workshops... lyk while visitng workshops u might hav seen ppls who sale rubbers, vipers rubber n offer u to get car comound or make ur mirrors or lights shine...
do ask ur mechanic, or shope from u purchase ur car parts... some 1 might b knowing them...
other option is.. go to shop selling windscreen (even if they dnt do it,then can tell u a person who do this)... they will make a hole by drilling at the end point of the crack... and the crack will nt further increase...
and if crack is throughout the screen... then dont go for ''jugaar'' must change it ASAP...
