Don't have any advice regarding the issues above, but on the topic of remover:
I got a 10 oz bottle of creamy baby oil from the $1 store, lathered it on over the PAX and just let it soak in for about 20-30 minutes. Afterwards it barely took much hard scrubbing at all to get it off. For some areas I did need to do it a second time - but still didn't have to scrub harshly to get off.
I fully suggest trying this because not only does it get the PAX off easily, it makes your skin reeeeeally soft.
