Epoxy paint for priming panels prior to filler?

[Dave_EH]

Hi,

Just hoping someone can point me in the right direction.

I have some doors that I have bought that have some older panel repairs made to them, and have then been primed (unsure of nature of primer).

I wish to have these sodablasted so that I can have a good look at the repairs (they're a bit rough but at least it metal not rust), then prime them prior to smoothing out the repairs.

Can anyone advise on a good epoxy primer?

Final priming and top coat after panel repairs will be acrylic.

Is there something I can just brush on after soda basting to protect the metal?  Can it be an enamel epoxy primer if I am to use acrylic at a later date?

Hope this all makes sense.

Spray chief make an epoxy primer 4 to 1 mix that is self etching and can be over coated with either 2 k or acrylic the only epoxy that I known of that can offer this...... after blasting the local blaster coats the metal with a clear product than can be left for up to a couple of years if stored out of the weather I believe Por 15 also makes a similar metal sealer ......FC427........

Hi I've used Wattyl super etch on my cars. It can be painted over acrylic or 2k it is great stuff. Highly recommended it.

I used an epoxy primer which can handle most top coats......Is there any reason you are using acrylic top coat instead of 2 pack?   We used epoxy primer and then 2 pack top coat. The primer then 2 top coats if it's a straight colour. This epoxy primer was used immediately after sandblasting to protect. There is a product called Oxydene that panel beaters use...unsure of the spelling. 

The repairs and any filler can be used over the top. I used the advice of my local auto paint shop. I'm told that 2 pack will last longer than acrylic and no buffing required at the end.
We applied the 2 pack in a shed ourselves and got a good job....not a show car though. My only regret is using a white primer which shows at any chips. Anyway that was 2 years ago and the paint job still looks shiny and good.
Best o' luck.....Moe`t
