How weather resilient is Gelcoat

[SwiftyDS]

Hi

I’m getting close to finishing my MRS200 build and have a separate build thread underway.

A quick question for other Tribute kit owners - how weather resilient is the gel coat on the panels as it comes out of the mould? I’ve dropped a mail to Chris at Tribute as I was planning to run it for a bit when MOT’d before getting it painted but so far apart from removing the flash lines and a bit of localised filling/sanding around the rear lights and doors it’s as it came out of the mould.

It will be garaged went not being used but do I need to worry about water ingress into the GRP if it’s out in the rain before it has a base coat/primer?

Many thanks
