oh for sure that why I never bother with mine cuz its too far gone (though dirty old bastard has done a job at leaking a lot of shit in one spot that's probably fairly well sealed lol) I usually see 2 types of guys doing the work. one dumps a bucket and rolls it out done in 15 min. the other seals cleans and seals cracks before sealing. if your spending the money I'd find the second one.
