ive got a 9 inch crack in my ground effects what do i need /need to do to fix them

 

we need some more info to help.

how did you get the crack?

where on the ground effects is it?

are your ground effects made from fiberglass or some kind of urathane?

 

If it is fiberglass, its an easy fix, just get back to us, and youll be on your way.

 

Take the part off. Then run some fiberglass behind the crack. Let it cure. Then apply bondo(or some higher end equivilent) over the the front and smooth it out. Repaint.

Easy.

 

the way i used to fix small cracks was to tunnel out the crack about a 1/4 inch per side and about twice as deep then cut small strips of mat the size of hte tunnel and build it up level. then i would cut a few larger pieces of mat out and cover over the whole grinded area let it kick off and sand it down then bondao that mo fo up and prime it, it allways worked for me give it a try

Drill a hole at the end(s) of the crack. That way it dosent continue to split then do the fiberglass/bondo work.

 

take a grinding wheel and roughen up the suface on the back side. Then lay some fiberglass matting on the back side. Youll be fine. easy fix

This would be the best way to do it. Although it may be overkill(it's what I would do). What I used to use was something we called "angel hair". You take a peice of fiberglass and cut it up into real small pieces, then mix that with your resin. It makes kind of a thick goopy fiberglass glue. Then lay a thin piece over the top and sand her smooth when it cures. Also reinforce the back with some thicker matting.

 

I use this stuff called West Systems Epoxy. It is stronger than the fiberglass and if done properly is very easy to use and very strong. You can find more info about it here:

It's most commonly found at boat supply stores

They have different fillers and uses instead of using bondo, which is soft, and you can use it with fiberglass cloth or if you're really industrious make something with carbon fiber cloth.

BTW: I would rather have fiberglass instead of urethane because of it's ease of repair.

Doing alot of repairs... i have found that urethane is alot easier to fix when you know how. Not alot of people really know where to start with urethane... but with a good heatgun and the right glue... you're on your way rather nicely.
