por 15 paint? solvent

[charlie_brown]

so i am going to paint the underside of my trailer with the por 15 top coat before it starts to rust. it is a brand new trailer but they never sprayed anything under it.

i am going to use a hplv cheap throw a way gun from HF. but i need to use a solvent. por 15 wont send me there solvent. would any solvent work?

I would assume you could use an automotive paint reducer?

Use a urethane reducer from a body shop supply store.
