I'm attempting my first restoration and this video really helped me chose the first coat of paint on the bare metal!

I agree Im rebuilding a 87 XF Ford Falcon, I had a bit of idea what im doing but these videos are SOOO helpful. Thanks alot

Great discussion. I would say epoxy primer is better on steel as steel is so reactive. Otherwise etch primer is so much faster and easier to use on all other metals. I only use Sikkens etch wash primer though..

Thanks for watching and I am glad the videos help.

One uses reducer and the other one does not. This depends how thick you need the primer to be. If you are spraying a larger area, I would use some reducer so it does not spray out dry. If you are spraying a small spot, you can get by with the mixing ratio without reducer. At the end of this video, I have a link to the technical data sheet explaining the facts about 202. The link may also be in the description. Thanks for watching!

No, it is not recommended to put body filler over DTM. You should apply the body filer to direct metal. The only primer that filler can be applied on top of is epoxy. Thanks for watching.

As I see others saying in the comments, this is the most comprehensive video on primers on youtube. Good job and thank you!!

Yes, this will change the color. The best advice is to spray several spray out cards to see what effects it has and see which ones you like. Some color chip books also show you what it will look like with different base colors. Ask your paint supplier if they have something like this.

There are a lot of different paint companies out there. If you want to do something like this I would look over all of the technical data sheets to make sure they are all compatible with each other. At the end of this video, there are two videos that you can click for Shoplines epoxy and self etch technical data sheets.

[CarAddictGarage]

Yes, you can use DTM on top of filler or metal.

If the paint is in good condition, you can final sand with 400 grit and paint on top of the sanded surface. Epoxy or self etch is for metal. So if you are not stripping, you can skip this step.

Great video, you answered alot of my questions. Based on what materials to use over bare metal and body fillers. Thanks for sharing your knowledge with us.

Are they using epoxy as a sealer before painting? That will be fine, but if they are applying self etch, then epoxy, then primer surfacer....I don't know that there is a benefit. Unless there is a paint company that recommends that. I know with PPG or Shopline that is not necessary.

@DIY Auto Body and Paint 2 years later to my last comment, i can reveal that i sprayed a metal drum BBQ in my back yard with both epoxy and etch primer in 2 seperate halves on the drum lid and 2 years later the etch primer wins, no rust coming through wheras the epoxy has rusted.
The BBQ drum was left outside in all wetahers totally unprotected

Great video, Donnie. I use DTM for large areas and aerosol self-etch on small things also.

How do you clean the steel panels prior to applying epoxy? Do you use hydrochloric acid? Some people have mentioned corrosion breaking through epoxy. Naked hands are a no-no, but perhaps a acid application followed by water and degreaser would solve that issue. What do you think?

Wanting to paint my kids bike. Handlebar looks like chrome mirror finish. If i wanted to paint it should i use self etch primer and so if, only need self etch prior to base coat

I have been putting epoxy primer on bare metal for 40 years...mostly PPG DP and then the newer DPLF. I had to learn the hard way, stripped a car to metal and applied lacquer primer surfacer...this was in the 70s. A year later it was flaking off. I like the ability to apply body fillers over it. I guess Iam old school....I have put some DTM product on bare steel but not sure how it will stand the test of time. Tried to locate the Shop Line product...that I think is a off shoot of PPG....cant get it locally....they tried to shove Omni off on me. You did a great job a explaining the the products...
