I looked at the data sheet and still not sure.
It says 10-15 min dry time between coats.
How long can I wait to recoat without scuffing first ?
A couple days ?

You can recoat at ANY time you like!!
Just depends if you want the paint to stick or not smile.gif

If you exceed that certain recoat window you wont get the proper adhesion between coats.

You have alittle fudge time but NOT MUCH,without knowing the product Id say any longer then 30mins you need to scuff. According to PPG when dealing with k36 which is their urethane primer after 30mins you need to allow the product to setup and then scuff before you can reapply more product.

The only product that I know of that can be topcoated after a few days without scuffing/sanding is DPLF epoxy but then Id scuff it anyway...Eric
