can I spray a coat of spi intercoat over my blend panel, then throw Nason over top, or no? I usually use Nason on cheap jobs and bump up to chromabase for others, so can either of these be sprayed over spi intercoat? Also, would blending a solid red be challenging at all? I'm assuming since it's not metallic or anything it shouldn't be very hard at all. I plan on going from the top of the quarters down to the first body line, then adding intercoat with my red, then shooting that down past the next body line in an effort to match the freshly painted trunk that's a touch brighter than the quarters. Thanks for all the help!
