Right then PLEASE do yourselves and others a BIG favour by listening to what I have to say on hull prep,believe you me it works.
Right then this thread has come about due to me spending the day with a blunt instrument scraping paint off a hull,and believe you me this is the fourth in a week all due to one thing BAD PREPARATION.
But i hear you all say well i do it this way and it works for me,all I can say is ............does it
Right then when a Grp hull is badly prepared it will not show up straight away,it is only when you scratch the hull or need to repaint it that problems occur.What happens is that water gets underneath the paint and you get loss of adhesion,not apparent to the human eye,unless of course ti is peeling off in great chard's!!!!!!!!!!
HULL PREP
1 Go out and buy youself a gallon of spirit wipe ..you gonna need it
2 Wash off all traces of mould release wax.Wash off the hull with SPIRIT WIPE to get rid of the mould release wax .Fairy liquid not good enough.
3 Start rubbing down the areas that you need to work on,ie the inside of the hull with 80grit to get a key for the glue to adhere to,outside where the shaft and
rudders come through 180grit
4 Wash off with spirit wipe and dry
5 Rub down the hull with 180 then 240 then 400 ready fro the PRIMER yes you do really need this stuff,simply fro the paint to stick to!!!!!!!!!!!!!!!!!!!
6 Wash the hull down with panel wipe
7 Prime the hull
8 Rub the hull a guide coat of satin black LIGHTLY not a full coat
9 Rub thus down with 600 or 800
10 Rub the hull down preferably DRY with 600 making sure that you get rid of All the black guide coat
11 Wash the hull with panel wipe
12 Paint it with colour of your choice
I know the well it works this way for me brigade will say it but hey come on do you in say 12months or less want the hassle of oh what do I do now,My guess is NO
