Paint Pens Before Hotcoat

Hey guys, I’ve been reading through the archives (you could spend a good year there!) and I think I have my answer but would like to be sure before I start!

I’ve done my cut lap and glassed both sides of the board. I have no idea how but when I glassed the top of the board some blue resin (from the resin tint I did on the bottom) dripped onto the deck. There must have been a bit left on the squeege or something (DICKHEAD). Anyway I want to just dab some white over the blue drips (the top of the board has no tint). I was going to use the bosca paint pens. I was also thinking of re-doing my pin line (which I painted onto the deck). Once again just onto the fibreglassed surface.

Will this be okay or might it run during the hot coat. I think from what I’ve been reading that this will be okay but I just want to be sure. To much work’s gone into board number 6 to stuff it up.

Thanks

Mick

BTW: This place is great! I hope one day I can help out others like you’ve all helped me!

 

Chase the dream, not the competition!

 

Posca pens are used on the hot coat then protected with Clear Spray or Gloss?

It shouldn’t run from the hotcoat so you will be ok if your just covering up.

If not applied too heavy you can cover the blue resin on the lam with the white paint pen and hot coat over.  It should not run.  I would not attempt the pinline, just because the texture of the lam from the cloth will make it impossible to get a clean line.  I regularly pinline with paint pens on the hotcoat and gloss coat over, so you could do it this way.  The downside to this is that you have to sand to 400 at least where you will be pinlining.  Anything less and you may get bleeding under the tape.  Going back to sand off the bleed through is more of a PIA than sanding to 400 in the first place.  The other difficulty is not sanding through the pinline when sanding your gloss coat.

Make sure you sand your pinline just a touch (using 600 or so) until the shinyness is gone or you may have some separation problems if you are using epoxy.

Not really necessary, but can't hurt anything I suppose.  When I get a spot where the resin pulls away (on a pinline or anywhere) I just take my finger (with glove on of course) and rub the epoxy resin on the spot.  This method is per Greg Loehr's instructions both on this site and his video.

Man, thats a good tip,  I missed that one.  Thanks!
