Hello there and thank you for your attention
English is not my main language so I apologise if my explanations are not as accurate as it should be.
I did my first mould and infusion since 10 years and it resulted as a disaster. I hope I can find help/solution and my experience could help other people.

I did the mould of a little tray with green tooling epoxy gelcoat and epoxy moulding paste on a glass. I used filling wax to fill the gap between the edges and the glass as you can see below:

So I did the mould, did my first infusion and had this as a result:


I forgot to take a picture but I had a looooot of bubbles  visibles behind the vacuum bag.
I did the infusion as this: [ -- Dry Reinforcement -- ] / Peel Ply / R100-MP22 Perforated Release Film / FM105 EasyFlow Infusion Mesh / Vacuum Bagging Film
I can see too there is a difference of thickness 



Perhaps I'm wrong but I think the problem comes from me doing too sharpen angles with the wax. I think it results with air traps.


What do you think guys? Am I right? Don't hesitate if you have any other clue to solve my problem, I wouldn't want to influence you

If yes, I was thinking about putting back in place the original tray (to protect the mould) and sand the gel coat where there was wax to flat this and to have this sharpen angles rounded.
I think it's possible to had the same gelcoat if I go too far or if I need to had a gap filled, can you please confirm?

Thank you mates, I have my other mould (unimould) done with the same way so I don't dare to do the infusion if it's for the same result

Thank you very much for your answer, because of you, I'm on the good way:

I did another infusion yesterday using the spray tack and taking more time to put the reinforcement in position and it looks really better: no bubbles at all on the surface


The problem is the fact that the tack stay visible on the surface even after an alcohol cleaning, looks like it's inside the resin.
On this photo, I used 2 layers of polish (coarse and fine) but no sanding, perhaps it would remove it if it s still on the surface....

I still have a problem , I think I have resin between layers so same problem than the beginning but not in the cosmetic layer. I thought did it well this time but the thickness is inegal on all the edge surface. That problem is a lot more visible on 2 corners :/
