Epoxy and powercoating - coating inside of rails

[focusedontheprize]

So the frame is off to the sandblaster this weekend. I have my epoxy primer arriving on Friday so I will be all ready to cover it as soon as I get it home from the blaster.

My plan is to spray the complete frame with epoxy, complete my metal work where I need to (i.e. fill holes, weld in the IFS and 4 link, new crossmembers etc.) and then re-coat it with epoxy to seal everything. I want to make sure the frame is sealed so I do not have to worry about flash/surface rust.

Here is my dilemma:

I wanted to sandblast the frame so I am starting with something fresh. I wanted to also make sure I had a coating inside the frame rails so eventually when I box the frame - the inside of the boxing is protected. I also was debating on having the outside of the frame powdercoated (if I could).

The issue I am mainly running into is if I epoxy the frame then I probably cannot get the frame powder coated because I have heard they go into the oven after blasting to push the oils out of the frame and this would then burn the epoxy primer off inside correct?

Anyone who has experience with this will be a huge help. Thanks.
