I took everything down to bare metal and existing plastic filler with stripper followed by 80 grit on the DA. I then went over that with 120 grit on my DA sander. Feathered it best I could. I then cleaned it with grease and wax remover. I then shot it with PPG DP50LF (DP402LF catalyst) epoxy etching primer. I got great atomization with minor adjustments to the gun at 45 psi. I like the results. I will be covering that with a Sherwin Williams 2 part urethane epoxy primer/surfacer. I will then come back over that with the PPG primer mixed for sealing. Body work will be done at a later date, after the car is on the road. After that will be the BC/CC. Respirator works great ! graemlins/thumbsup.gif
Thanks for all the tips graemlins/waving.gif

Kevin </font>[/QUOTE]I'll look again, but I'm pretty sure it is a urethane based epoxy primer... :confused:

Sorry for the confusion. Here are the specs for my primer/surfacer:

PRODUCT DESCRIPTION:
ULTRA-FILL II® P48/P49 are premium quality two-component acrylic urethane primer-surfacers designed
for high build and fast filling of repair areas. It is ideal for repairing today's "high tech" basecoat/clearcoat
finishes where gloss holdout, resistance to sand scratch swelling, and adhesion are critical. ULTRA-FILL II®
sands easily without clogging the sandpaper and provides excellent adhesion, corrosion protection, and
color holdout. ULTRA-FILL II® when used with ULTRASOLV® Reducers or AS8 meets U.S. National Rule
Requirement of 4.8 lbs/gal (575.04 g/l) maximum ready-to-spray VOC.
TECHNICAL DATA:
• Color P48 Gray • Volume Solids (sprayable) at 8 : 2 : 1 34.9%
P49 Beige • Sprayable Viscosity #2 Zahn 26-28 sec.
• Air Pressure 30-40 psi • Lead/Chromate Free Yes
• Recommended Dry Film Thickness after sanding 2.0-6.0 mils • Sandability Excellent
• Humidity Resistance at 500 hours No effect • Gloss Holdout Excellent
VOC Total VOC Less Exempt
lbs/gal g/l lbs/gal g/l
• Maximum VOC as applied at 8:2:1 with US1-US5 4.75 570 4.75 570
• Maximum VOC as applied at 8:2:1 with AS8 4.70 563 4.70 563
SURFACE PREPARATION:
Bare Substrates: Properly treated Steel, Galvanized Steel*, Aluminum, or Fiberglass.
*Note: With the inconsistencies of galvanized steel, consult your local Sherwin-Williams representative for
system recommendations and substrate testing.
1. Solvent clean with SHER-WILL-CLEAN® Solvent Cleaner R7K156, AQUA-MATE® Low VOC Surface
Cleaner W4K157, or UltraClean™ Surface Cleaner R7K158 and wipe dry with a clean, dry cloth.
2. Apply 2-3 medium coats of G.B.P.® Etching Filler E2G980 or E2G983 or one double coat of
CORROSION SHIELD™ E2G973. When using E2G983, for maximum corrosion protection, MET-LMATE
® W4K289 may be used as a pretreatment.
Prepainted Substrates:
1. Wash surfaces with a mild detergent in hot water. Rinse well and wipe dry with a clean, dry cloth.
2. Solvent clean with UltraClean™ Surface Cleaner R7K158 or AQUA-MATE® Low VOC Surface Cleaner
W4K157. Wipe dry with a clean, dry cloth.
3. Sand repair area and featheredge using 80, 180, 280, and finish with 320 grit treated sandpaper (or Pgrade
equivalent) on a random orbital sander. Use UltraClean™ Surface Cleaner R7K158 to remove
sanding residue before recoating.
4. Apply 2-3 medium coats of G.B.P.® Etching Filler E2G980, E2G983 or E2G973 to bare metal and body
filler. When using E2G983, for maximum corrosion protection, MET-L-MATE® W4K289 may be used
as a pretreatment. Or, treat bare steel areas with MET-L-ETCH® Steel Cleaner W4K288 followed by
MET-L-MATE® Phosphate Conversion Coating W4K289. Treat bare aluminum with DUAL-ETCH®
Metal Cleaner and Conditioner W4K263. Treat bare aluminum with DUAL-ETCH® Metal Cleaner and
Conditioner followed by Alodine® 12011.

John, just something to remember when you are appling different brands of paint. Later down the road and if you have problems WHO will warrenty that paint job.????

I promise you that PPG wont either will S-W. Why should they when you use one product from PPG then another from S-W then topcoat with PPG. They'll look at you and laugh all the way home!!!

Ive seen it happen to guy there in town who painted his sons 67 mustang. Used base from PPG then didnt have the right hardener for the PPG clear so he bought clear from Dupont cus the PPG store was closed. The base lifted, called PPG to look at the paint, rep came out walked away laughing.

Just becareful cause you are playing with fire sooner or later you'll get burnt.

Unless S-W has since changed numbers in last year, P48 primer is NOT epoxy based. DPLF primer is NOT etching primer either, its only epoxy based. If it makes you feel better I really did like P48 primer, when we switched to PPG

If it makes you feel better I really did like P48 primer, when we switched to PPG My PPG paint supplier is advising me on which products to use. I asked them which PPG primer I should use over bare metal and plastic filler and they told me DP50LF. I also told them that I had a gallon of the P48 "Acrylic urethane" primer surfacer that I had bought previously and they said I could use that over the DP50LF. After that, I could use the DP50LF over the P48 as a sealer before BC/CC. Is this info correct or am I really making a big mistake (all warranties aside)? :confused: I was advised on this forum to find a PPG supplier and let them advise me as to product and application. :confused:
I can obviously use all the recommendations I can get, thanks ;)
