finishing

Post by toolman »

Could anyone help, I've sanded a little too far and gottin into the fiberglass.When I did another layer of epoxy I can see the cross-hatch pattern in some spots and blotches in others,what can I do to fix it ? one person who builds canoes suggested sanding to feather it out and add a patch but said you may see the patch. HELP please! :(

Well it doesn't appear to be worn through of lifting off the wood. Is that happening anywhere?

Before you do that try going over some of the area with another coat of epoxy.
Dust will get in the indention's but will disappear when you put another layer of epoxy down.
That is one reason I always fill the weave and then run another coat of epoxy over that.

thanks I'll give that a try before Itry the sanding.that just seems like a lot of extra work to reglass some spots, I guess working in QC at Toyota for 20 years makes you a little more fussy about fit and finish

Re: finishing -

(Didn't want to start a whole new topic just for this question/comment so I used this 'finishing' thread.)

Ever since I began planning for my JEM Trapper canoe build, it has been in the back of my mind to laminate (epoxy) some real birch bark onto the outside panels (above waterline - below waterline will be graphited).
This would be strictly cosmetic - I suppoase a bit show-offy - but I would really love the retro look. I would not be using the fiull thickness of bark, just only about one to three layers.

But I probably won't even try this, because I suspect the birch bark holds too much of some oily resinous substance that might work against the epoxy process.
If you've ever burnt (or even smelled) some birch bark you know what I mean.

This is such a crazy idea that I doubt it has been tried, but anyhow I do ask: any comments on this?

Thanks.

(now it's getting warmer weather I will be orderiing my epoxy and glass and wood flour from RAKA real soon.)

I got me a plan now, soon as I get my epoxy, I'll epoxy a scrap piece of plywood, let it cure, sand it, and then epoxy on some inner layer birchbark, then when that cures, I'll store it under water for as long as it takes to build my canoe, then if the birch bark test piece seems entirely okay, then I'll do it to the otherwise finished canoe.

If I do end up using the birch bark, I'll probably use some graphite-darkened epoxy to imtiate the lines of pitch along the panel seams of an old time birchbark canoe I'll probably do that anyhow with or without the birchbark.
