Top coat ( min 2 coats )

For the non-skid use fine silica sand ( by the sh*t load ) bury the first layer of top coat with sand, 24hrs later vac sand and apply top coat until the desired feel is achived.

It will look awsome, but ya got to use sand liberally
So you don't think is is necessary to wash the surface with epoxy to fix it.

You must figure the hi-build primer is good enough?
Are you assuming I'm sanding all the gelcoat off or just cleaning it up.

No I don't think it's needed, the high build is a really good foundation, once you've done the fairing/sanding and sanded first coat of epoxy primer, look close for imperfections and spot those with a good epoxy fill,( should be minimal if any ) then do your 2nd coat of primer and sand that, at this point your deck should be/will be smooth as a baby's butt.

I assuming you are sanding just enough to prep a good bond for your first coat of HB, if you do sand threw the GC, it's no biggie, just avoid sanding into the glass.

To quote some goofball on TV, " you're gonna like what you see "

If I sand through the gel coat aren't I by definition into the glass?

So I'm thinking to just not grind any more glass than necessary,yes?

Or is their another layer between the gel coat and the glass?

Not really, when the GC looks semi translucent you know you've gone far enough and you may not even need to go that far

you shouldn't be grinding any glass, even when grinding down the non-skid you should try not to go into the glass, you should be able to grind the nibs ( which is mostly resin ) down before you hit any glass material

No,not really

Re: Paint gelcoat

Have you used high build before ?, it will undo all your sins made with the sanding or grinding

Anyone make a good high build besides awlgrip. I have a couple of dinghys I'm working on.
Not needed but I would like to see how it behaves.
