October 30th, 2007 06:09 AM #12if you want the whole video compilation of polymer prodts inc, it is available sa store nila for about P400.
pero the lectures done by "go fast fiberglass" shown in you tube have better styles.

October 31st, 2007 08:44 AM #14maamoy lang ito pagmali ang timpla...overreaction ng polymers. otherwise the smell is tolerable.
the materials/chemicals also have short life (2-3months) storage lang so you don't overstock on these unless gagamitin mo na agad.

October 31st, 2007 07:20 PM #16correction...pede kang magkalung cancer for inhaling the fibers. the fibers are made of glass and once it logs into your lungs it can not be removed.
use the proper facility and mask when cutting and grinding these materials.
I just did a demo/basic lecture (last saturday) sa mga kakilala ko sa TR3 (a forum ng toyota enthusiast in region 3)...pero i did this demo sa bahay ... in angeles city.
if you have watched the demo above and a few more in you tube done by GO FAST Fiberglass... you already have a 90-95% grasp of what to do or what you need to know.
A few details left would be:
1) What equipment to use - a clear disposable plastic & popsicle stick as stirer, a brush (yung gawa sa balahibo and not plastic fiber)
2) Para mare-use mo yung brush, always immerse it in lacquer thinner after use. Para hindi ito manigas.
3) Determine the right polymer premix to use that fits what you want to produce.
4) 1:3 ang general rule of thumb sa fiberglass:polymer resin. So if you will need 1kg of fiberglass for your product, you will use about 3kg of resin. The cost per kilo of fiberglass is about P120-130 and resin ganun din.
5) Different fiberglass have different densities. A typical fiberglass mat is about 300grams per square meter area. So if you know the surface area of your product, you will roughly know how much fiberglass and resin do you need.
6) If you over mix the hardener of the resin, it will produce the bad smell and will be very hot (after about 10-15mins after mixing). Follow the instructions of use - 1-2% lang ang hardener ng resin.
7) ALL fiberglass product is first layered by a GELCOAT. A gelcoat is a bit different than a standard premix polyester resin... but it adds beauty sa finish product. Iba rin ang mixing directions nito before use.
8) GELCOAT must be layed one time (so if big surface it would be best to use the spray gun as demo sa "Go Fast". Ang fiberglass laying and resin naman pedend bit by bit.
9) Mix only what you can do in 5-10 minutes because each (gelcoat and resin) will only have certain "open" working time. After that, magseset na ito at difficult na gamitin kasi sticky.
Those basic info above will be about 3% more knowledge.
Maghands on ka na, to learn the rest on experience.

October 31st, 2007 08:47 PM #18start with anything small muna.... kick panel ng speaker ng car perhaps,
Yung seminar ng Polymer Product is SULIT din naman... kasi hindi lang naman plain fiberglass laying and production ang topic dun. If you have the time and money, go for it.
