Thanks for sharing the Plascore info. It may be the best deal out there if youre going to get stuck with freight.
Bob , what is the number on the hardener?

first layer of fiberglass cured. Will need sanding before 2nd layer. Fiberglass did not completely ad here to the edges. Re-wet and wait 2-3 hrs for tacky- rubbery the stick down w dry wall knife? pipe clams and visqueen covered cauls? hope to get next layer on today

Not sure what this means.

So you had issues with it sticking around the edges. Plastic sheeting and a 2x4 down the edges would cure that along with a little weight.

Sandy
The fiberglass/epoxy overlapping the 3/4 sides of the plascore didn't completely adhere to the sides. I'm asking how to fix this-
1) and rewet the fiberglass- let it get rubbery and try to stick it down again with a drywall knife.
2) re wet then use pipe clamps to clamp a visqueen covered piece of wood along the edges to keep the fiberglass in contact with the edges until it sets.
3) just sand re wet out apply 2nd layer of glass/epoxy and the do 1 or 2 above

sanded down to 180 grit- smooth
I noticed that the dried fiber glass protrudes 1/16 to 1/8” from the edges-guess I didn’t get as close as I thought w the trauma shears! I don’t think this will be an issue on the chime edges-as those edges will be trimmed down to be parallel to the forms. Do you recommend a block plane for plascore or is there another method?
I was thinking of using a trim router with a bearing and a cutting guide to clean up the gunnel edges.
Your thoughts?

I mentioned this to Bob already in a email. For the group it's worth mentioning the best way to trim excess fiberglass, where it runs wild past the edge of plywood or Plascore, is to trim it with a fresh sheetrock knife a few hours after layup, then it's tack free but still rubbery and soft.

will be mounting hull sides on forms as soon as my helper gets back from her errands! Just trying to wrap my " 3d space relations impaired brain" around this. beveled edges go towards the bow on form #1 and towards the stern on form #3.

Sides on- the Three Stooges would be proud. needs some minor tweaks- too hot and sweaty to mess with it now. Plascore does not hold screws well- I'd recommend using Sandy's advice about using 1x1 squares of 1/4 scrap plywood to keep screws from digging through the plascose.. Feel like a full days work- had to rearrange my shop to have working room. one side of my garage it taken up by the work table and the other by the boat!

Ah hah. I was going to tell you that about making space but thought you’d figure it out quickly. Looks good so far.
