I have never applied filler so this is all new to me. I have researched how to properly apply the filler and believe I have a good understanding of the process. The Rage Ultra/Rage Extra 50/50 mix provides a long working time but can get rather pricy. I have seen several positive endorsements of 3M Platinum/Plus here but the 3M website says it has a 3-5 minute working window. That said, is it possible or advisable to mix small batches and apply them over a large area in a section? If so, do I need to sand as I go along or is there a window in which the product will adhere to the previous application? This will all be done over SPI epoxy within the 7-day window. The temps will be in the low to mid 70s in North Florida when the filler is applied.
Thanks,
Emil
