GMH cracking in corners of visor

So I've started painting my GMH, and I'm noticing now that the visor area is trimmed and sanded, the corners of the eye slits are showing stress cracks as the mandibles spread apart.

I'm hoping it's just the resin outer layer, and not the fiberglass (I doubt it...), but does anyone have any ideas to reinforce the cracks so they don't get worse?

I'm thinking of adding a layer of JB Weld on the inside, behind the cracks as insurance. But if it's not through the fiberglass, should I just let it be?

Thanks

Wow that is odd I have never seen that happen before can you post some pics.

Yeah. See below. I only noticed this when I sprayed the silver layer (it's so shiny, it shows everything in hyper clarity...). Kinda pissed. I haven't even painted it yet and it cracks.

does the one crack go all the way down to the ear?

Yup. Looks like it.

Wow all that from just cutting out the visor. I would recommend re-enforcing the inside with glass and use glazing putty on the external cracks to fill them in.

I agree with deadland. Reinforce the inside with a layer of glass and ujse bondo spot glaze putty to fill in the cracks. It should hold up fine, especially if tis is one of the glass GMH helemts to begin with.

Thanks guys. I'l give it a try. ::sigh::

Install a temporary visor while you paint it, then replace that with a real one when finished.
It will save you a lot of heartache later.

I do THIS everytime I paint BUT i just use the visor I plan to use covered in painters tape! NEVER paint a helmet without a visor installed...BAD idea because of this EXACT issue the OP is having.

It depends if you can see the crack on the inside of the helmet , Id take a guess that it is just in the gelcoat layer, (its a fiberglass helmet?) best way to fix this would be (Provided it is only a surface crack) use a file and gouge out the cracks through the gel coat layer youl see the gel coat is most likly white and the laminate layers yellowy colour, , so gouge out the cracks and remove any gel coat if it is loose, then fill it up using an 2 part epoxy resin let it set then sand smooth and you may need to refill and resand,
If the crack goes through you will want to add some glassing to the interior give the area you plan to glass a good sand with coarse grade paper, like 150 or 180, youl need to do this as one fiber glass has set it tends not to bond well when recoated with resin again, so the sanding will create a key for the resin to hold, paint on a coat of laminate resin on let go tacky, then brush another coat on, lay some glass cloth down (youd be best of getting some chopped strand matting as apossed to the fiberglass tape and tearing a few strips of it out prior to starting) once youve brushed the resin down, lay the glass matting down and brush some more resin on to it , you may want to do a couple of layers of matting , once it has set to a firm state sand down to smooth it upthen add another layer or 2 of laminate resin

And like every one else said its good to keep a visor in whilst painting

Thanks, guys! I will repairing and making sure there's a visor in there while I paint!
