Fixing a few dock dings. I have the stuff here from Spectrum Color. Instructions are pretty basic. I'm familiar with adding and mixing catalysts. I've got my putty knife, rags, hairdryer, sanding block, 400, 800, 1000, 1500, 2000 papers, my Porter Cable polisher, 3m compound, 3m Finesse It, and wax ready to go.

My Questions:

1. Temperature. Is there an ideal temperature - or minimum temp? - I'm working in a garage, but believe it or not it has been snowing here in Atlanta all day. I know from working with West Systems epoxies, temperature plays a huge role in cure time. I'm in no rush to do this if warmer weather helps.

2. Filling. Using a good putty knife, should I fill it flush? or should I expect some shrinkage - and therefore overfill the repair? (No that's not a cold weather reference).

3. Any additional advice is appreciated.
