Form,

From reading your posts, you seem to be a hobiest like me who is in no huge hurry to get to the next step and wants the best possible results. If I am correct, just use reduced epoxy. The induction time is very important, some are even inducting epoxy over night.
 
There are pos and neg to both. For the 2k sealer its easy to spray, you can denib or sand it in 10 minutes, it locks up fast so you can base and candy over it quickly and it fills defects and sanding scratches better. The epoxy doesnt do any of that but the one thing it does do is make awesome adhesion. Your base will bond better and if you have a difficult to prep surface with nooks that you cant get in too good you really dont have to worry too much. Your paint will stick anyway.
 
thanks guys. strum youre right, i am a hobbyist, rarely in a hurry and i want the best results! induction time with epoxy is interesting. i noticed if you safely warm it up and mix real well it helps the induction/mix. epoxy and i are good friends although painting in the cold with it sucks. i do light blocking with epoxy and have filled small chips and pinholes with it. i also have no problem pumping it through my lph 80 with 1.0 tip, it just has to be warm, i also pump it through my airbrush too (reduced)! is 2k less temp sensitive, and what is the recoat window?

They are but 2k is more of a generic term for urethane primer. Its not really a term used for epoxy even though it does fall into that category.
