Re: [chillysurfer] Home Depot Pink Foam; too Spackle and ...

Pink corning foam, isn't that XPS?   Like the blue dow foam I use sometimes, right?

I've only used it for rail buildups, but here's my experience...    For bonding I epoxy directly over it, no spackle since the pores are really small.   I also left the finish rough for maximum bondage.   I think I only went to 60 with the sanding.   Too fine a sanding and you're taking away the "tooth" for the epoxy to bond to.

If you don't like the color, tint over it.   I bet a red would work really well.   A blue would probably make some kind of purple.   When I did two layers of a dark red over the blue dow rails, it made a light purple after one layer, then a nice deep maroon after the laps overlapped.    I would be hesitant about spraying anything that might interfere with the bond of the glass to the foam.   I understand XPS is a great ride, but delam if you look at them funny.   My advice would be to keep your color in your lams, hide the pepto-pink that way.  :)

I'll be watching for the photos.
