Hairline cracks in roof over the cab.

[Headrush]

Hi,
I have noticed several hairline cracks in the section of plastic roof that goes over the cab section of the van. This piece is slightly domed and can't take any weight without flexing.
Does anyone know of a flexible clear lacquer that I can spray over this section to seal the cracks?
I don't think they leak but I would like to be confident about that.
Thanks
Alan

Any photos of the area?

Are you sure it's not fibreglass?

It's probably fiberglass, but it looks like the typical vacuum formed roof section that is common to a lot of motorhomes. I just wanted some kind of easy fix rather than something fiddly like captain Toller which is good for small rigid areas.

Yep

I used this on the slight cracks on the roof of my motorhome

I don’t think there is anything simple, if the area is flexing that is the reason for the cracks.

Yeah, that's what I've used on other parts of the van, but I'm looking for a spray coating really. I guess any modern lacquer should do, but I was wondering if anyone else has done anything similar, and what they used.
