Repairing fiberglass., tips on doing it. Options

[My2Celi]

So i decided to not return the relica trd wing. If you dont know what im talking about here the link.

So i talked the guy in maylaysia and he said he used 5 layers of fiber glass. he sent me pictures of it before he mailed it out and i guess it might be the mailing process. iono but who cares he gave me back some money for the crappy work. So how do i fix fiber glass crack? bondo? fiberglass resin? please help me guys.

kinda hard to tell by the pic but it looks like it's just the gelcoat that has cracked, if it is you can prolly just dremel the crack until you reach "solid" fiberglass and then use something to build it back up.
Dunno exactly what bondo is but i often use stuff from plastic padding, sure they got a few products you can use

thanks for the reply. bondo is just a name brand here in the state. its body filler most applicable for car dents. i dont think this person is using gel. i can see the fiberglass already. do you think i can just use fiberglass resin and go over it?

TRD wind is formed out of 6 pieces (whole wing), Center piece is formed from 2 molds, then you form it - you form a top part mold, then donw part mold, and after they cure (not fully, but curing process is almost almost done) you put these 2 molds together, and to glue both up and down sides of the spoiler ussualy people use special type of glue witch consist the dust of fiberglass, and small cuts of fiberglass fabric. SOME people who make FG parts simply do not use this and glue these parts together using simply the resin. The result of this leads to your PICS.

Same molding is for sides of the TRD spoiler - they are molded from 2 pieces and then glued together. If the product is done right, ussualy manufacture DO NOT spray primer on it, just sand the gluing line on the part, and you still can see it, if the gluing process wasnt done right - ussualy manufactures use bondo on the gluing place and then primer all the part.

In your case to fix your spoiler (and NO its not only gelcoat cracked, it is cracked fully im 90% sure), just dremel out the crack place as much as you can, clean all the dust. THen take the resin, mix it up, then take the fiberglass, and cut alot of pieces as small as posible in the resin of the FG. This way you will get some sort of mixture of the FG and resin in one place. Then put this mixture all over the crack and IN the crack area. This should help to keep these 2 parts in place. Let the Mixture to cure compleatly before sanding.

But im almost 100% sure, that after painting and lets say after a month or 2 of driving with the spoiler - you will notice more cracks all over it.

Conclusion - really really poorly manufactured parts witch will give you a headake along the run.

that doesnt sound so good... is there a solution to where it won't crack? like place another layer of fb on the 3 pieces.
