Fiberglass resin to coat new trailer bunks?

[Darren Nemeth]

It is finally warm enough outside to paint and to set fiberglass.

I have wood at the ready for the badly needed new trailer bunks and I have two options for sealing them.

1. I can go to the local stores and get a quart of Glaspar weather sealer varnish for $15 or

2. use up the last remaining quart of my poly fiberglass resin and add the wax to it.

The resin will definately save me more money and it has been in the now rusted container on my porch all winter since September. I don't know it if will good enough for glassing.

Will it be okay to go with the resin and wax on the new bunks or would I be better off spending the $15 for a quart of Galspar in which I will never use all up?

i used PT wood and left it unsealed.

you have mat for the resin? won't stick long without it although i wouldn't use it if it has frozen. i can't imagine that's good for it.

Folks said it woudl be okay to leave the resin on the porch. I had my doubts but did it anyway. It is over 9 months old so probably is no as good as it used to be anyway.

ondarvr would know

my bunks flex a good bit, i'd lean toward not using the resin for that reason mostly.

Okay. Looks like I'll spring for the all weather sealant. I can use what is left of it on the porch, too.

My last boat trailer I bought some Trex decking to use instead of wood.

If you want to make a good penetrating sealer, mix up some epoxy resin thinned with MEK. Personally, I would just use pressure treated wood.
