I could use some experienced advice. I have my hood, rear bumper and rear spoiler to paint. I am using "Omni AU" MBC white with the clear. Question: I want to be able to prime all three parts so I can sand again and get ready for the color and clear. However I do not want to paint all three coats the same day. I would feel too rushed as I am an amature and do not want to screw up as the prep is all the work. My main question is that I was sold DP48LF epoxy primer. I was told that it can replace using a flex addative. PPG's P-196 sheet says this is true but only if you put one coat reduced at 1/2. And if it is over DPX801 ect. plastic adhesion promoter. 1. Do I need the 801? 2. I am afraid one coat will not allow me to "fill" slight scratches ect. that are a little to deep to sand down through. Dose reduced 1/2 mean the ratio is 0.5 to whatever the total amount of the mixed ratio is? For example - primer 8 oz., catalyst 2 oz so the reducer would be 5 oz's? 3. Would I be better off using a more standard primer on the flexible parts with a flex add. so I could take my time and sand were necessary and insuring good coverage? I would then just use the DPLF for my hood. Lastly, dose the DPLF sand like a regular primer would? It also says to reduce with DTV Reducer, I have MR reducer both fast and medium. Are they compatable? Any help is appreciated as I do not fully trust the well meaning advice that I get at my supplier. Dale :)

 

Dale, I really can't answer your question because I've only painted with stone age lacquer. But I can point you to a place where you can get some expert help. Go to http://www.autobodystore.com and go on their forum. When I was learning about painting I got a ton of good advice there. The forum is much like this one and has a lot of semi pro and pro painters and a few company reps. I'm sure you'll get all the answers you need there. Good luck with the project.

 

ok i have a little experience on this subject. I believe the flex ad has little to do with the sanding process and the amount of time you have before you have to put the base coat on. I believe it actually has to do with the plasticity of the primer and how flexible it is. First you shouldn't have to put the base on right after the primer. Corection you shouldnot put the base on after the primer you should let it dry and then sand it till it is extremely smooth. However the base color the white in your case has to be put on a short time before you spray the clear. Because other wise it will look flat or the clear will not bond... So in other words prime wait a day sand and then base 20minutes to a max of an hour or maybee 2 put the clear on. This is how i have done it and the paint turns out Beautiful. :thumbs:

 

Thanks for the info. Also, that is a great web site. Thanks

 

I used the DP50LF on both my bumpers. I didn't change the mix. It's been two years and still looks great.
