What is the prefered method of order here?? Epoxy prime the prepared metal then fill over the primer preventing any moisture from ever reaching filler??
Or, fill the prepared bare metal surface and epoxy prime over the filler???? I have heard pros and cons both ways. Dave ![]() |

Good question. I fill over bare metal, then prime. I've never had a problem in the last 20 years(that I know of), but then, I'm not a professional. I just do it as a hobby, and for side money. I'd like to hear a pro's opinion though.

I'm no pro. When I did mine, I welded in the panels, filled the seams with fiberglass and sanded. Then primed and filled with filler. Sanded and primed again. Worked for me, although I still haven't got to the painting!

Well, I guess I would call my self a professional. I have about 63 General Motors certificates and ASE master certified and every I-CAR collsion certificate you can think of, but who cares right. The proper way to do body work is. Well, let me start over. The way I would do it and others suggest is to, for example: strip a door to bare metal, sand over any metal areas you will do body work over with 50 grit on a da sander, prime with ppg dx171 over bare metal, after it tacks up you have to spray an epoxy primer over that while it is still wet. When dry you should have at least a 2mil thickness. This will ensure you have proper "corrosion protection". Next lightly scuff sand where you will apply bodyfiller with "Evercoats" new body filler that you can apply over painted surfaces and finish body work. Of course you will probably break through some areas while sanding your bondo but not as bad as putting it over bare metal. Finish your body work with 180 grit and then apply thin coat of "Evercoat" metal glaze and coat over entire area where there is no bare metal showing. Sand again with 180 grit. Primer, block, primer until done. Just a recommended procedure but I have done it both ways.

When all else fails---read the instructions!!!
Good advise from 72CSTC5...but, always get the manufacturer's spec sheets from the brand/type paint you will use. Stay with one system all the way from start to finish.
This will insure you have the best "tested" procedures & compatibilties. The paint suppliers will give you these sheets when you buy their products. There are some different companies products that will not work well together. |

Now, I'm no expert but, the product sheet for DP 90 LF (PPG's epoxy) specifically says not to apply over dpx171. I don't know if this is the same as dx171 or if the procedure or product has changed, but just goes to show that you must read the manufacturers sheets. It does say you can apply over dx1791 wash primer or dx metal treatments. Michael
