i have 3 words for all u awlgrip nay sayers.
BLAH, BLAH and BLAH.
yes, it requires finesse and is hella expensive but there is no question about it.. u get what u pay for.
u have a few options based on how pristine you want the finish to look.
1. sand (with 400) the entire hull
2. fill and fair any significant cracks in the existing hull
3. wipe down the hull with lacquer thinner (or similar)
4. visually inspect for highs and lows and cracks (what u see at this point will be visible later)
5. address anything you consider unacceptable
6. prime the hull with awlgrips high build primer.
7. sand with 400-600
8. wipe down (again)
9. roll and tip 3-8 coats depending on how flawless you want the finish.
if you want or need advice when u get around to address the primer and paint
, let me know and we can talk at whatever length you want.
btw: i agree with the rest that a survey
is necessary to confirm it is only cosmetic.
