What reducer for Polyurethane

[LX Kid]

I bought a quart of INSL-X, Sila-Thane Polyurethane Enamel paint and was wondering what reducer would be good for rolling and tipping on my transom? "They" said to just use acetone and that would be fine. After doing a little research it seems that's not the best choice for polyurethane and Forida's hot humid weather. I was thinking of using Intralux #333 and was wondering if anyone has any suggestions? Thanks

High temps call for slower evaporating reducer, high humidity swings it the other way, you need a faster evaporating reducer.

As a test I would try what the manufacturer recommends, they normally know more about the exact product than anyone else.

If you need something slower check and see what other similar products use. Auto paint supply stores can help.
