OSPHO & EPOXY PRIMERS

I Have Been Told That Ospho And Epoxy Primers May Have A Chemical Reaction Resulting In Proplems. Because Of A Time Delay From Media Blasting To Applying The Primer I Need To Seal The Metal (fl. Humidity). If I Use Ospho Can Any One Recomend An Epoxy Primer That Will Work Okay. What Else Might I Use To Seal The Metal For A Couple Of Weeks Until I Can Applyan Epoxy Primer??

Thanks
Andy

If it were my car.

Due to time delay I would leave as is parked in garage and when ready to epoxy, I would sand the whole thing with an 80 grit DA clean with wax and grease remover and spray the epoxy (two coats)

No epoxy does not have a problem with the acid as long as the acid is neutralized properly. Dried films (not properly neutralized) of acid cause problems with everything from filler to epoxy to 2K primer to acid etc primer. Adhesion and curing.

Save your money and forget the acid.

Thanks Barryk

I Think You Are On The Right Track. I Can Keep The Media Blasted Parts In My "dry" Shop As Well As Covered With Moving Blankets. I Don't Think They Will Devlope Enough Surface Rust That A Little Elbow Grease Can't Take Care Of Prior To Priming. I May Even Put The Parts In An A/c Controled Room. I Just Worry About Any Kind Of Rust.

I Think There Are Primers That Are Not Effected By The Ospho But The Primer Of Choice Is Ep. Correct??

Thanks Again
Andy

You're right Andy, epoxy offers the most compatability and durability. Just make sure you get the metal cleaned and textured before you apply the first coat.

Once the vehicle, whatever it is, is media blasted, it won't really take that long to sand it with a DA using 80 grit to prep it for Epoxy. Well worth the amount of work, to have the correct starting point for the rest of the repairs and finishing.

don't use Ospho (search the knowledge base)...it's a last resort "try" to slow rust on parts that can't be blasted/sanded etc (inside "A" pillars?)

Barry's correct, leave it alone, (April's pretty dry) the day you spray sand all with 80 grit if it's only 2 weeks approx

if I have to leave bare sheet metal for more than a month (in August!) and do some handling/fitting...I do spray it with a light coat of Duplicolor rattle can "self etching" primer....BUT... I use the green color as a "guide coat" to sand back to bare with 80 grit the day I spray the epoxy

(ha!...did get one past the wife once....she never did find the parts stored 6 months under the beds in the A/C cooled house)
