I ran out of slow reducer. I'm using Tamco Glamour clear coat that calls for 4:1:1 mixing ratio. I have some touch ups and small parts to paint. Can I use Medium reducer with a slow hardner (activator) in mixing the clear coat? Tried to google this issue but didn't come up with anything. Temp here today will be 65 degrees outside. Garage temp I expect to be about 70.

 

I found my answer:

Match Reducers and Activators

Of course, not all clear coats are as thin as you would like straight out of the can. Adding a reducer to the mix can help thin them out. However, you’ve got to make sure that your activator matches the reducer. Slow reducers should be used with slow activators, and so on. Everything evaporates appropriately that way.

 

Makes sense. Thanks for sharing what you found.
