Some Damage & Lousy Repair Idea
Someone cuts an access hole, then someone taps the hood too hard - CRACK!!!!
Clean, then Grind or Sand Damaged Area
This shows a section that was removed and a resulting crack, who knows what came first? Part was cleaned & damage ground
Troth 1-2 in wide on frontside
Make a V groove for the new glass/resin, afterwards, flip & do same on backside, if possible.
Another view of the prep
This view shows a drill hole at the end of the crack, this is a "stress relief" that stops the crack from growing.
Make Gravity your friend & Ventilate!
Position the part so the resin stays in place, it's liguid & runs easy till it stiffens up. Use of a fan can help.
Light Cardboard Template is easy
Here a cardboard template is made for a replacement piece. Someone apparently cut a hole in this hood?
Save old fiberglass pieces for repair
I have some pieces to re-use on my repair, transfer template info & cut
Prep before you mix the resin
Here you can make out pieces cut to fit repair, latex gloves & cheap paint brush
Position parts & almost ready for resin
Back side is supported with masking tape & entire crack to limit loss of resin
Resin & glass in place
Paint the damage with resin, lay in glass, paint on more resin, saturate glass & it turns from white to transparent
Add Heat
Sometimes you comeup a little short with the hardener mix, I add this radiant heater to help it along. Be carefull!!
Another Repair Area - Before
This crack needs attention.
Another Repair Area - After
I like to use resin & glass, sometimes followed by tiger-hair and lastly bondo, more work is needed for sure.
Hole repair is simpler.
Drill counter sinks to achieve bevels or grind away to bevel edges, tape backside & fill with matt, cloth & tiger-hair.
Roomy enough I hope
It was hard to tell what to remove & what to leave? Hope this works?
gravity is your friend!
Remember to let gravity help you. Position part so resin stays where you want it.
