[pelican]

usually what causes the paint to peel - poor prep

fiberglass hulls require dewaxing and scuff sanding,prior to painting/coating
this process is often skipped - end result,paint peels and pops off


now:

if you're having the boat blasted:

after it's blasted ,it's gonna require a finish sand,to remove any remaining paint residue.

after that,solvent wash,and barrier coat it

do the barrier coat like this:
start with grey,and alternate coats of grey and white - this assures complete coverage
you want that barrier coat to be 10m thick - use a matchbook cover as a guide

number of coats means nothing,thickness does - one coat of barrier does nothing...
