Re: How do I begin to go about fixing this?!
If possible, it is often easier to use the metric system & adjust the MEKP % for the temp you are working in. Above 60 is best, but you can trick the resin by keeping it inside & warm until just before mixing, so even working down below 60 can be done.
You also need to make sure the surface you are applying the resin to is above 60, and stays above 60 until the resin cures. In near 60 temps, you can often use a halogen work light setup below the area to be worked. Those lamps get HOT, so not too close to the hull, or any plastic/tarps draping the work area.
Using the metric system, start @ 1.5% MEKP, so in 50ml of poly resin(nearly same volume as 2oz) you'd use .75ml of MEKP.
Cures too slow, use 1.75% MEKP for the next mix
Cures too fast, use 1.25% MEKP
In cooler climates, you might start at 1.75%, in warm maybe 1.25% for the 1st mix. Using metric & percents, you can fine tune the MEKP & kick rate much easier, IMHO, esp when you are mixing larger volumes of resin, then using ounces & drops of MEKP.
You can stage additional setups of resin & MEKP so you can quickly grab, mix & use additional resin if you need to. Rather then having to measure it out as you need too. Just try not to setup more then you can reasonably use.
As soon as any 1 layer sets up & tacks off, you can apply additional resin, lay additional glass, & wet out an additional layer. It does increase the bonding between layers to have them cure as 1 multi-layer layup, then individual layers. Too many layers too quick can also speed the reaction, overheat the layups & weaken the laminations. On a small repair, in 70+/- temps, I don't think you'll overheat the repair.
But laying up 6 layers of 1708 & resin across the entire transom in 95+/- heat, yep, that may be too many layers too quickly....
Having 1 or 2 small projects, on standby, but ready for resin, allows you to use up left over mixed resin, rather then making artistic statements w/ the
waste:
Tape on til cured
