Bondo shrunk on me three times before I figured out the trick

I was doing a quarter panel repair on a 2010 Civic last Tuesday and kept getting pinholes after sanding. Drove me crazy for about an hour until a guy at the shop told me to mix the hardener just a tiny bit less and let it sit 5 minutes before applying. Smoothed out perfect first try after that. Any of you guys run into shrinkage issues with certain brands?

Let it sit 5 minutes" - is that really a big deal though?

Got the same issue with Evercoat products. Mixed the hardener a hair under the recommended amount and let it sit for 10 minutes before applying, fixed it right up.

@lily57 yeah it matters, let it sit or fight pinholes all day.
