Thread: Fiberglassing Tips?

Thank you, very helpful. When I was talking aboyt layers I was talking about fiberglass layers (how may layers, and how thick they would be), But thank you for the advice on the paint. I was going to need it later.

lol aright..cool

I've got a new question for the fiberglass pros out there. I'm thinking of buying a used fiberglass hood of which I will sand, repaint, etc... , but the thing that was originally wrong was it has paint bubbles. Do you think it was something in the fiberglass that caused the bubbles, or was it the paint?

I'd really like to know, because if I get the hood and repaint it, I don't want it to bubble again on me. Anyone know?

I really doubt that its something in the fiberglass. I think it was the type of paint used...but then again...im not an expert

I've been browsing through this forum and learned some pretty good stuff.
I've done a few fiberglassing projects in the past and I'm getting ready to start one on my younger brother’s truck this weekend.

Here is something that might help some of you making speaker enclosures that will cut out a lot time from the process. I don't think anyone has posted this yet, but I didn't read through everything:

Fiberglass mat sucks to work with. After you have applied resin to the material that you stretched over you speaker rings why ruin a nice smooth surface with mat. There is fumed silica power called Aerosil, that when mixed with fiberglass resin and hardener creates a thick paste. You can then cut out a small section from the back of the enclosure, dump this stuff in and spread it around with a cheap paint brush making sure you get the corners where your material comes into contact with your speaker rings, sides, back, etc. You can repeat this as needed making it up to as thick as ¼’’.

That was kind of a quick and dirty version of that process. If you would like some more details let me know and I’ll try and help you as much as possible. I’m looking for the link that I purchased my Aerosil from. Here’s a pic of what the bag looks like.

that was really helpful, appreciate that find

has anyone ever fiber glassed in the middle of the winter?
Was wondering if the extreme -C temperatures effect how reason goes on and cures... and if it effects structural properties when it's done drying...?
My garage in not heated and i need to fiber glass my trunk later this year...

I would try to keep the temp above about 60deg. If you do have to do it in a cold garage use a space heater and heatgun to keep it warm. Don't start a fire.
