I barrier coated my boat about five years after purchasing new. I had a company sand blast the bottom to get everthing off then we cleaned,prepped the bottom to prepare for barrier.
Once spring temps got high enough we got going,after five coats, over two weekends I was ready to kill whoever talked me into this process. About $2500 bucks later we aere ready to paint. Two more coats of bottom paint was using Trinidad at the time we were ready to launch.
Reward was I did noyt have to paint bottom for three full seasons,only side toch ups.
Felt a lot better now, switched or to water soluable Aqugard bottom paint covers grt in just a coat,uced that for several yrs & its grt paint for the bucks. Clean up body nice simple water!!
Full barrier coating process not sure if totally necessary in our climes,,however made me feel better that the hull was now pretty wateright . I had a 33' foot boat and at times it looked bigger than the Queen Mary when your on your back for a day at a time!! I always hated that aspect of spring launch & still do,but at least for three seasons I could stan upright and paint the toch up areas!!
