Fiberglass question

[Skools Out]

more coats will never fix that issue now as it can't soak in threw the current epoxy. you could try drilling several small holes in just the glass in those areas and the pump epoxy in and let it bond the areas together. drill size i wouldn't drill any larger than a 1/4 hole. drill an inspection hole anyway to see if it is a vold or just a flush issue that made the epoxy to drt milky from moisture in the air or air temps. it may be find as it is if it was just a temp / moisture issue making it milky.

I cut away a little piece that I know was a bubble and forced resin behind it with a brush, it worked. I know it is not a climate issue because I only work with the resin/glass on dry sunny days. It seems like a pain to do that in all the areas but i may have to.

Yet another reason Blue Runner is not a glass man.

But I do admire you guys who are!!!!!

I have had that happen before. Not a good situation to say the least. I was sure that my surface was clean and prepped (ground with 40 grit on grinder). The glass and resin were new and everything was dry. I believe the substrate(plywood) wicked the resin out of the glass before it had time to kick. Moisture can also cause the glass to fail to properly wet out but if you are sure it was once clear like the surrounding areas the super soaking capacity of the plywood might be to blame. Try to coat the area with resin before laying the glass in. If you were using poly resin I would say to mop on a hot coat first by thinning the resin with acetone and adding a little more hardener to enhance penetration and soak the plywood before proceeding with glassing. I am at a loss with epoxy.
On vertical work I have seen the resin run out of the glass before the resin kicked up it is not for the faint at heart. If you catch it early enough you can recover. (ie get frantic with the bubble popper and resin)
In your case, it is really about sealing the wood and it is structural. There are a couple solid milky areas that need to be redone IMO.
I don't think you will ever get it to be clear and free of air. Prepare to itch. Good luck.

I did put two coats of resin on prior to adding the cloth. The cloth was added a week later. I will post a pic of the outside which came out perfect. Yeh I think it will never be clear, I just want to make sure the bond is good.

I am not professing to be a pro. Just observations of what I think I experienced. Since you coated the wood with resin two weeks before the plywood soaking up resin theory is a bust. What produces the beige like color I see on the picture of the outside? Did you thicken it with cabosil or something?

When you get to the fairing stage of this project. Systems 3 makes a nice product called Quickfair . . . it's an epoxy fairing compound. It goes on like butter and sands nicely.
