I was thinking of taking my frame and having it dipped and then Ecoated. What makes me lean toward this way is you coat inside and outside. I was told it is as strong as POR 15.
Anyone done this or have an opinion ?
Electrocoating is a painting method which uses an electrical current to deposite paint. Here is a link that explains it better. E-Coat
I was told also this paint is very tough to get off once it is applied. The only downside is if the frame is pitted it will cause a rough surface and the cost (~1k for chemical de-rust dip and paint)
All modern cars get e-coated after the body-in-white is assembled, before it enters the paint shop. It's for corrosion resistance. Like ckerch said, it uses electric current to bond the coating to the metal, at an electron level.
This is different than powdercoating? I thought powdercoating also used electromagnetic fields and paint powder.
From what I understand the frame is dipped into a tank of liquid paint. The current flow draws the paint to the frame. Because it is liquid it gets inside the frame rail.
Where as, powder coating is a dry paint sprayed and then baked. The corvette retoration business that I am thinking of taking this to, said I could apply a powder coat over the top of this E-Coat. The benefit would be the powder coat would fill in any pitting on the frame. Since I am not building a show car I don't plan on going with the powder coat. Kind of over kill IMHO.
By dipping the frame,I suppose you mean chemical
dipping.My question is,how do you remove all the chemical residue from the inside of the frame so that the epaint won't have the problems that are associated
with the areas that might contain the chemicals?I like the idea of painting outside-inside of the frame

Yes, I do mean chemical dipping to remove both rust and paint. I did not ask about removal of residue. But I saw a frame from a 59 that just came back from the Ecoat and looked good and uniform without any bubbles, residue or bare metal showing. I know the chemical dip and the E-Coat are done at different places. I also know the restoration shop goes over it in detail before they send it to paint. I just not too familar with the dipping process but would hope the restoration/parts place would check about residue.
I still don't know if it is worth the $$$ to get the inside of the frame coated which is the major advantage of E-Coat process.
