Advice needed

[mickpin]

Hi all having a bit of a problem just stripped Antifoul paint And there seems to be some sort of other paint underneath which is being awkward to get off
All help and advice would be appreciated

[jeffstevens763@g]

Would have thought that was a primer

[mickpin]

Do you know what I would use for that ?

PM nugent on here he does this kind of stuff knows his onions too I do know it's a pain to remove and you won't get it back shiny without a re coat but nugent will know.

I've had good success with plain old standard cellulose thinners and plenty of rags keep it soaking and it softens and comes off
Bit messy if your doing a large area but if its smaler patches then worth a try 25 ltrs is about 25 quid so not expensive and handy for all manner of things

Will that not harm the gelcoat ?

[jeffstevens763@g]

found this, not a job i would want and doesn't leave a good finish

Got the antifoul off it’s just the same of the primer will not come off . Should I use something different to get it off

[jeffstevens763@g]

never anti fouled for this reason, plus always kept my boats ashore but looking at this applying anti foul in reverse your hull will be pretty crap looking when all the coating is off leaving two options a respray finish to get a shine back or re-anti foul i would have thought unless someone knows different

Gelcoat is like new underneath

[jeffstevens763@g]

when you say new do you mean intact [no holes, damage etc] but it will still have a key for the paint to adhere or it would just flake off. i would contact someone like hempel to see if they recommend anything but i suspect as BK has said thinners but you won't get it out of the key leaving a dull finish, if you're wanting a gloss finish [back to original] its worth finding out if you can paint on top of what you have as a prep for a two pack paint.

Nope I've done a few and it doesn't harm the gel coat
I've also stripped a few that had little or no surface prep and required only a light flat off with 1200 wet and dry then a good polish with a rotary machine to get the shine back
I think a lot of rib people know they may want to return to gellcoat finish one day so don't go too mad with the surface prep
I've seen big cruisers that looked like they'd been rubbed down with a house brick to key them

As beamishken says, cellulose thinners, often sold as gun wash, will be OK on the gelcoat. If it's not too coarse under the paint, you should know that matt finish is faster than glossy. Just passing it by you...
