I was curious to see what Orange hand goop would do to my mold… well, long behold it helps clean, sand it a bit, etc.
u have to get the right one, ill see if i can snap a pic of the container. picked it up at harbor freight. 4 $?s for a huge bottle. it has an abrasive in it and helps buff out an area that either, gel coat got stuck (small dots of gelcoat), or paint, etc, or just plain ol sticky stuff.
BUT dont think its a buffer! u still need to buff your area out again. but it will not , i repeat, NOT damage your mold 
heck, it also cleans your hand while ur at it! great when u have tons of layers of tack spray on your fingers! =)
great stuff…
