What is the correct way to layer the fiberglass when fixing a crack?
Ive always "V" the crack. Then when I put the fiberglass mat in I went from smallest width to widest until the crack is well covered, then sanded down smooth.

after watching one of the car shows on TV, they mentioned just the opposite. Going from largest to smallest.

Which way is correct?
Thanks

I would go small to large. I want the innermost portion of the repair to have mat and resin.

thats the way I've always done my repairs too,

Are you asking a general question or do you have a specific repair? If so shoot us a picture. The final layer should have the strands puled apart a little to blend in. In stead of a straight repair line.

Thanks guys. I was really just asking cause I've always done my repairs , filling the glass from smallest to larger strips, pulled apart, and never had a problem. But when I was watching one of the many car shows on tv , the guy describing the repair he had done said he did it from largest to smallest, which was opposite of what I've done. I just wanted some additional input.

I also go from small to large...mainly due to I want my final layer of mat to cover the entire surface with one layer. So when I scuff it back...I am dealing with just THAT layer and not numerous 'rings' that can appear if done in the other manner. Which the other method can make it look like onion cut in half.

I 'guess' that may not matter due to when I get done with any lamination I always apply a layer of Vette Panel Adhesive on top of it to get it to how I want it and not have any exposed resin showing of any serious magnitude.
