While waxing today (I was not on the roof), I noticed these two small spider web (50 cent piece size) cracks. Is there any do it yourself fix for this or to maybe prevent it from getting worse? Thanks,

It will depend on how much you want to invest and the level of your own repair skills.
It does look as if it is somewhat serious, and I'm wondering why you have these cracks here?? Is there something pushing through from the inside? You need to find that out first, so it doesn't get worse.
Get to a boat or auto shop, that deals with fiberglass, and get an estimate.
You can buy fiberglass repair kits from most auto-parts stores, and you should be able to make the repairs yourself. Biggest problem will be the color matching, but, if it's on the roof, and not really all that visible, that may not be as much of a factor.
Good luck with the repairs..

I used Eternabond tape. I had 4 holes where a storage pod had been removed. I filled it with a little bondo, then put the eternabond over the repairs. No problem for over 10 years. Just a warning though... this is great stuff but if you put it on, you ain't gettin' it off. This stuff sticks like 'God help ya'.

The eternabond tape will certainly seal it. But it will also seal in some air, which will try to escape the next time your are at elevation, or on a super hot day.
There is a chance it will separate more of the Gel coat from the fiberglass. Once water gets in between the gel coat and the fiberglass, the delam will continue to spread. A lot of these roofs so have plywood or OSB inside. The gel coat is water tight, the laminating resin they used to make the structure is not. Water can/ will slowly seep inside. If it gets into the wood........
That type of gel coat delamination is either a sign of a good impact, or contamination after the gel coat was sprayed in the mold, before the fiberglass was layered on top of it.
See if the area underneath is soft. If it is, I would remove all the gel coat in the area, sand it down to bare fiberglass, re enforce it with more fiberglass matt saturated with polyester laminating resin. On top of the laminating resin, paint a layer of Sanding resin. Sand it smooth then just tape the area off and use some spray paint. This can be done for under 20 bucks. A roll of eternabond is what 55$
They do sell a spray on gel coat that cures like paint.
