New transom - gel coated now need to move some stuff - best way to deal with holes!!

[Fed]

How about parting with another trade secret GM?

How do you stop the goop slumping if you don't add a filler?

I found even with the talc it still slumped a bit.
Just checked my boat, when I got it I finished up with 17 spare holes in the port side of the transom let alone all the other spares around it.
Anyway, did quicky job on the holes that counted and haven't touched it since, you can see the slumped goop in the larger holes below.

I really need to go over them a little with a final smear, can I just rough up the flow coat then apply more over the top?

Hi Fed

One way to reduce "slumping" that I have used (and GM probably has others like heat and a little more mekp) is to stretch plastic wrap tightly over the wet patch by pulling and taping the edges with masking tape.

Use a squeegee smooth out the patch to remove all "waves" or high spots.

After the repair has cured remove the plastic wrap and sand with a block. If your still to apply gel coats use 150 grit, if you've applied gel you probably need to lightly sand between coats. If your at final gel coat stage lightly sand and feather edge the surrounding area using fine (240 grit). Then wet sand with 400 grit followed by 600 grit then use lambs wool to polish.

The taped plastic "cling wrap" system works well as long as yon don't apply too much resin or gel coat and you dont get too heavy handed with the squeegee. Wetting the squeegee prior to using it gives a lot more control.

Got to love FRP!

HaHa, I finished mine off with a flat bastard file and then went fishing.
