weather cracks

What's the best way to fill in weather cracks on a hood for prep to paint?

How deep are they? You need to sand the hood anyway, can you sand them out?

Sand it down and fill with FG rosin, sand smooth and paint over with a flexible paint.

I was going to fill it and figured it had to flex but wasn't sure with what or what to fill it with. What flex paint would you recommend?

Don't know the new paints, best to consult with a body shop.

There was a thread in "body/cosmetics" about a repaint that mentioned what he used.

I'll have to look it up. Bush of mine used a rattle can then laid like 6 cans of clear over top. Looks good but not sure how durable it was

Fiberglass "spidering" is near impossible to cover... and still flex without checking the paint. On older machines, once the gel coat on fiberglass cracks, that's pretty much it. An inexpensive alternative is to paint the surface black, as when the checks come back they won't be so noticeable. Come back they will... Adding an flex agent in polyurethane finishes certainly helps.
