Just used the interlux spray but want to hear other boaters experiences with the spray as well as the brush on trilux 33 brush on...PLease post your results here..Im trying to decide if maybe I should brush the 33 on but Ive already used the trilux spray and Im waiting to put it in the water. I used the Primocon prior to the spray....Also..Im considering doing My SS props too..Its a bravo 3..The barnacles didnt ignore the props either...stuck like glue. I hear it comes off but its some protection for awhile anyway.
