gelcoat spraying ...how old is too old?

[inveratta]

Just trying to finish off some mudguards..ok so not Michelangelo finish required....

I have some test mixes of sprayable gelcoat and tint from about 10 weeks ago ...stored under dust free conditions...obviously not catalysed...running short of time and material....can I use this mixed in say 50:50 with new material?

yes, tint won't have an effect on storage capabilities, after all, lots of white tint went in to make it white in the first place.

When we buy gelcoat it comes with a guarantee for 3months. After 3 months its still good if stored out of direct sunlight and in a cool place. Life span differs between brands. Do a test on a small amount. If the gel time hasnt drifted & theres no sign of crystalising it will be ok to use without mixing into new material. Its not really old so I would use it as it is, Just dont leave it too long.
Thats my opinion anyway

I think i recall reading gelcoat has a 12 month shelf life from when it was made

Or just do a good job with minimal finishing required.

Yep, he did a test spray with gelcoat(I would presume not on his work), didn't work and went to paint. Did I miss something gaz?

Not so important when it was made Gazza. Additives are blended into the gelcoat prior to sale.I repeat, We get 3 mth warranty from that time.
