@67Dart440GT What size tip do you use for sealer? I will be spraying a fiberglass topper for my wifes Dakota soon, and will only need to sand, seal, and spray BC/CC. I will more than likely use SPI epoxy, mixed to seal with.
Check the product sheet. Each paint producer will give you their recommendations on everything you need to know about the product and it's application. My guess would be a 1.3
