Epoxy Primer

Hi guys
Just wondering if someone could tell me what the best thing is to do after you epoxy prime a part. I just sandblasted and primed my Radiator
support with " Omni Epoxy Primer " and needed to know what kind of paint i should use for the finish coat. I realize i need a 60% or so gloss, but what kind. I used on my nova DP epoxy primer and its close to the gloss i need, but this Omni is Gray and it needs a top coat.
By the way has anyone ever heard of this Primer i am using and if so how good is it compared to DP Primer. Is there anything i can use on top of this primer that sands easy and has good filling qualities. I have some pretty bad pitting just under the battery tray area.I guess i could spread a bit of bondo, but would rather not. I use to use a heavy coat or two of old lacquer primer as it filled pretty good.
Any help would be appreciated

PS Does anyone know of a good on-line paint supplier. My local guy charges a fortune. A gal of DP with the hardner is 178.00

Try using PPG's high solids primer. Also check out Auto Body Depot.

I've not used the Omni primer. I have shot the Omni paint and it didn't seem to cover as well as the full-blown PPG paint.

I use the NCP271 (?) high fill primer with the catalyst from PPG. It sprays thick and fills pretty good. Almost reminds me of the old Featherfill from way back.

I would suggest getting the tech sheet on this. With the DPLF primers, you can only spray the NCP over DPLF with the 402 catalyst (it may be 401, I'm going off of my memory). The tech sheets for the DPLF and the NCP clearly state which DPLF catalyst you should use.

My local PPG supplier told me that the Omni paint is about 1/2 the price compared to the PPG paint. Great for bodyshops with pro's behind the gun, but I thought that is was real "watery" and didn't cover as well. Could have been just me.

Also catalyzed spot filler called "Icing" works real well on pits. I just finished a M/S 80 gas pump that was pitted really, really bad.

Hope this helps.
