Thanks to everyone who has responded so far! I will have to look into a tarp now from one of the places mentioned.

Today I went a couple of loads without talc just to see what would happen.  It worked just fine without talc so we will see what it looks like when it rains.

 I have a couple more questions.

1. Who has a 70 bushel tank and who has a 100 bushel tank? I want to see if this problem is with all of them or just the bigger tanks.

2. Who is/is not using treated seed?

Thanks again.
