PC, POR15 or Chassis Paint?

[Possmguts]

I was originally going to haul my frame to be sand blasted and powder coated, but I was waiting until I had the cash to do so. Since Ive had time I have been chopping away at it with the wire wheels and finish grinder and now it sits all nice and shiny inside and out and in all the tight spots so I was thinking of just doing the POR15 and top coating it. Ive been reading on the POR15 and it turns out it works best when applied Over surface rust. Who knew that POR stands for Paint Over Rust?? There isnt a trace of any surface rust now... This is Not something I plan on driving in any snow or rain so now Im thinking a good couple coats of Epoxy Primer and Chassis Paint should work just fine. If I send it to the powder coater now they still want to blast it so I didn't save any money there but instead wasted a ton of time doing what I've done if I decide to pay for the PC... But its as clean as its going to get and will take a paint job very nicely and save money for parts since PC costs is about 600 bucks or so. I know PC is much more durable, but like I said its not going to be driven in any snow or rain. Any input to would be appreciated... Keep in mind Im on a budget and Not going for a show truck... Just a really clean good weather driver.
