A friend of mine called me today to ask if I had ever experienced what he did in my time using fiberglass. I helped him build his door panels and the fabric we used for them is what he used today. He is molding the climate controls into the face of his glove box.

Long story short, he mixed up a batch of resin and after 3 strokes of the brush on the fabric, he turned back to see it melting a hole where the resin was. He had called me before hand to get the right mixing amount for the hardener and said that it took about 35 minutes to cook in the tub while he scratched his head wondering what happened so I don't think he over cooked it.

The only thing that he did differently was he used a little spray glue when he wrapped the fabric over the glove box and then put on the CA because he had run out of activator. Could the combo of CA, spray glue, and the resin have caused the melting of the fabric? Has anyone else had this issue?

what kind of fabric were you using???

Couldn't tell you exactly but it is relatively thin and elastic. Stretches in all directions.

The thing that makes it wierd is that we used it for two full doors and had no issues. I guess the other variable is that I wasn't there making sure things were being done correctly. hahaha

I've never heard of spra glue, CA and accelerator, or any type at any temp of resin melting fabric, but I'm sure there is a way... Typical spandex, I understand is mostly polyester, and I don't know how those things you listed could have done it. The temperature would seem more likely that a chemical melt, but you would see it smoking. Weird

what kind of resin? Poly or epoxy?
The only thing with spray glue, is that the resin would melt the glue. loosing its grip on the part and going to shit. CA glue, I never heard or seen issues...
OK... I just read everything over to make sure I was understanding.

Is the fabric the very same that you used or did he go out and buy more?
The resin and hardner, is that left over from the first job?
Oh shit, I just realized something.... You did the door panels with him, correct.
Did you also show him how to clean the brushes?
How to have everything ready to clean and use the acetone to thin down or slow down the resin.
Thinner or acetone will be the blame here.If he had his brush sitting in either one before he glassed, it may have beed over satuarated, melting the fabric. Some materials out there that are thin will melt with thinner or acetone..

The dummest question is the question you didnt ask!

I didn't even think of that.

He did the piece again today and I told him to call with any problems. So far my phone is quiet.
