Using epoxy primers

I've just recently found out about SPI products & after researching the internet for a few days decided to try the epoxy primer for two purposes ( 1. sealer 2. under hood & truck lid, fender wells, etc} I'm not a pro @ auto painting by any means but I have painted 2 of my trucks & one enclosed trailer over the years. My current project is a 59 Vette that I've owned since 1984. I started restoring this car in 1986. I disassemble the car sandblasted the frame, etc & coated it with epoxy primer & urethane black paint' Also stripped the body down to the glass then coated it w/ epoxy primer & high build acrylic urethane primer. That was+/- 20 years ago. It has been setting in my shop ever since. I am retired & getting older everyday. In Dec I decided that I needed to complete this project while I still can. So I have sanded down all the body parts to 600 & i'm ready to seal it (using reduced white epoxy primer) for bc/cc & paint underneath the body, engine compartment, inside trunk lid, hood, etc w/ black epoxy primer. I curious if more experienced people might see something I've missed or have any recommendations concerning this? I purchased both epoxy primers & reducer today. Thanks for any suggestions or advice...........
 
Shine should chime in..................hey that sounds good. No kidding aside Mr Shine who is a Vet guy is the man you want to listen to.
 
For areas you are doing sounds good to me, I would keep the reduction around 10% or less due to the age of material on there.
 
did you redo the seams ? that is all i can add because my system on vettes differs from most . keep pics coming of your progress .
 
I would have to say basically no on the seams, has I remember there were no cracks in those areas & all the bonding strips were intact. I did repair all the cracks to the best of my ability & reinforced areas i.e. over the front wheels which seems to be a common area for developing cracks as well for other areas. May I ask what your system entails? Thanks for your feedback....
 
i use epoxy only on glass. the crack at the center of the wheel well is a bonding seam . if chemstrip was used i believe it weakens the bonding agent which leads to shadow seams later. on a white car it wont be that noticeable. i redo all the seams simply because of the age of the cars now.
 
We finished applying the black epoxy primer to the engine compartment, trunk, fender wells & underneath hood & trunk lid. The primer went on very nicely & looks great. Yesterday I sprayed some of my dash & other parts with the white epoxy primer. When I opened the can the of white which looked sort of separated on the lid (not the same as the black did, just seemed odd). I mixed 10oz (1.1) waited 30 min & other than a couple of operator errors these look good also. When I was cleaning my equipment I noticed that the reducer I used (2 different ppg med urethane) did not disperse with the primer. This did not happen with the black. I was able to clean everything with a little elbow grease, but after cleaning all of the primer off everything it was in the bottom of the container totally separated from the reducer. Looked like oil placed in water. So is there something I missed or is there another reason (wrong solvent) this happened or nothing to worry about?
