Hi,
I tried repairing some damage to rudders and daggerboards on my Tiger and the short strand fiberglass filler came out quite soft. This time I coloured it with what I assume to be the proper stuff.
The polyester is probably 2 years old and the hardener and colorant cream are probably less than a year.
I mixed the colorant so the result was reasonably close to white. Is this the culprit? Or maybe was a too chep with the hardener?
I wouldn't recommend putting colorant in the resin - it only stands to weaken it. Make the repair and then paint it afterwards. Cheap and old are not two characteristics you want to have with a resin either!
