By using catalyst(Isocyanurate) in formulations is to control things like cure-time as well as make the paint stronger, more resistant to things like compounds, chip resistant and UV damage.
Can you let me know what paint system you are using so we can test it.
Is it BC CC, single stage or acid cat...etc.?
We have all the testing and weathering equipment so we can get 10 years of weathering data in about 2 weeks. If it is a system that is currently in the market I should have all the data without having to test.
This would be a good topic for the paint section.
Slick67: Let me know what paint you used (PPG, BASF, SW, Akzo) and I'll let you know if you will run into any issues.
Sorry to go off track!! I Don't want to give you any bad advice.

Hey Nuke, don't know if I can wait 6 months......I'm impatient!! hhahaa
RBC67, I used PPG for everything from the metal up. 2 coats of sealer, 4 coats of primer, 4 coats of paint, 4 coats of candy, 3 coats of clear. I used all 3M to cut and buff after wet sanding first with 1500 then with 2000 and 2500 on a couple of places that were thin and didn't want to go too deep.
