I have some upcoming repairs to perform around my Impex Assateague’s skeg box, as you’ve probably seen in some of my previous posts. I now have the supplies to do the job, so to put it off any further would constitute procrastination. I have a pretty good plan in mind to effect the repair, but despite being handy and technically competent I have little experience with fiberglass and gelcoat.
The I’d like to make up a few larger batches to colour match three different colours on my boat, plus a smaller repair on another. I’d like to then catalyze a small amount for the repairs while keeping the same colour for future repairs, or to make small adjustments to if the colour is not acceptable.
questions at the top of my mind right now are regarding the storage of gelcoat with added pigments but no added catalyst. Do I need a perfectly air tight seal? Are there particular container materials that the gelcoat will chemically react with, and thus to be avoided? Is this even a worthwhile thing to do? What’s the shelf life of gel coat in general?
