I have a habit of learning the hard way, I would like to to hear of things, even if you think they are common sense, that can make the process difficult. For example, don't use foam finishing pain brushes to apply resin, seemed like an ok idea at the time. I should have figured it would melt. Anyways, thanks in advance, happy holidays.

The most valuable thing I can tell is you is take your time. If you're not a good painter or don't have the proper equiptment have someone paint it for you. It doesn't make sense to do all that work and have a sloppy paint job(If you're going to paint it.)

Don't let the smoke out of your equiptment..it doesn't go back in.

These are the things I wish someone would have told me:

1- Make sure you get the shape exactly as you want. Don't plan on "I'll fix it later" that will waste days of your time.

2- Mixing the resin hot is better than not having it harden at all. lol (Please tell me I'm not the only one!?!?)

3- Don't hold back on the resin. You don't have to make a big batch, but prepare to make more than 1 batch. This means always keep extra paint brushes on hand.

3continued- Just gob that resin on to your felt or what ever. Keep pouring that stuff on till it is saturated and just dripping all over the place.

4- Bondo... I think the thing people overlook that is the most important is the sand paper. GET THE RIGHT GRIT SAND PAPER AND GET ENOUGH SAND PAPER.

sanding.... sanding... oh the memories of FG lol

I just got a spray gun kit and now I just need the compressor. How much pressure is required to use a spray gun?

Hell yeah. Hot batches, does that mean that it doesn't really take 2 or three days for the resin to harden? Are there any don't do's when using F.G.? -- posted image.

smonster your spray gun should have came with the specs for it.. if not get on the manufactures website....

i agree you can never have enough resin.. i always have to mix more and then i will mix to much the last time.. but no need to let it go to waste

Dont make a design with super tight tolerances when the fleece in put on, because once you fiberglass it your subs, or speakers may not have room beside them anymore to fit.

WEAR A RESPIRATOR! fumes and small fibers may not seem like it, but they cause damage to your lungs! Don't risk it, buy it, use it.

DO NOT MIX MEKP AND ACETONE - this causes a fire.

Yep, I found this out the hard way. I started with 120 grit and worked my way up. Primed it and painted it only to find that I should have started with 40~60grit. So that's what i did. I found that a random orbital sander works GREAT! Also, hardware stores sell this little rubber/wax like blick that is used for cleaning out the sandpaper. It works wonders. I was able to use a piece of sand paper far longer then I would, or even could have used it without cleaning it.

I don't know if it's been mentioned sinse it's so obvious, but don't eat the FG Are there any don't do's when using F.G.? -- posted image.
