- Well I finally get to spray some epoxy on some of Ruby's bare sheet metal so it will be totally protected from corrosion and rust. Today we cover my thoughts on proper panel preparation to receive Epoxy Primer and I get to try out my new spray gun spraying the epoxy.
If you have a project you would like to showcase at the end of one of my videos just email me a few pics and a short description to: foothillpaintandfabrication@gmail.com

Very impressed with your work, but more so with the fact that you manage to keep that shirt clean!
Lots of bleach and spray and wash! I have 5 shirts and they aren't that great up close but I try to keep them nice.
Thanks
Mark
Lookin good 👍
The video I needed to see. Thank you.
Thanks. Be sure to read the spec sheet on whatever product you choose and if you aren't sure get the paint reps info and talk to them personally. Most people behind the paint counter are not painters...
Amazing prep work, thanks so much for taking the time to share and teach. Happy Thanksgiving!
You are very welcome and Happy Thanksgiving to you and yours.

Cool beans Mark. I'm learning a lot. Thank you for your time.
As I have mentioned before my experience has been with metal fabrication and welding. I have very little experience painting and I appreciate your input and perspective based on your extensive knowledge on the subject. Thanks for sharing your expertise on this subject.
You are an excellent communicator. I hope you and your family have a wonderful Thanksgiving.
Thank you Lyle, I have the ability to be in contact with experts in the field and want to pass along what I learn and of course from all these years of experience. Things change and we don't do it like we used to for good reasons and I want to share that with you all. I feel like the more knowledge you have the more confident you will be on your own project and take some of the worry out of all of it.
Happy Thanksgiving to you and your family.
Mark
that was a good video !
Thanks, glad you liked it.
Happy Thanksgiving
That's pretty exciting Mark! I know you were chomping at the bit to get some spraying done. Thanks for showing us the process! Happy Thanksgiving!
Thanks Doug, Happy Thanksgiving to you too. Yes it was nice to break out the gun and do some spraying.
Hi Mark, very nice series. Did you record doing the inside of the truck lid with primer surfacer? I have been trying to find where you did that. Thank you for the videos.
Hi Jason, do you mean the underside of the hood on the 50 Chevy?
Hey Mark, good video. What are your feelings on using Acetone as a wax and grease remover? I feel it might be less expensive than a product specific for cleaning metal, prior to shooting primer. And it evaporates very fast.
Hey Charlie, Acetone would be less expensive but also less affective. It evaporates way to fast defeating the purpose. Wax and grease removers are designed to lift the contaminants up so you can wipe them away while still wet. Basically they float the bad stuff so you can wipe it off. I have used lacquer thinner in a pinch too. If you can get it in your area Prep-All is really good and costs about 35 bucks a gallon. I can't get it here any longer.
Great video Mark. This is likely what I’ll use on the 49.
Will this epoxy be the primer for your paint system also? Or will you apply another type of primer over the epoxy before color?
Maybe you already answered this, but I don’t remember!!
Great question Robert. The answer is, I don't know yet. Epoxy has a bad reputation of clogging sandpaper (rightfully so) but I asked the paint rep specifically how does it sand, his response was "it sands well". I haven't sanded anything I sprayed yet but will more than likely do a video real soon so we can all find out. Ideally using epoxy all the way would be more bullet proof but expensive and if it doesn't block out nice then I won't be using it other than a sealer base.

Usually you use a reduced coat of epoxy just before spraying color. You can spray sealer over epoxy, poly, or 2k. I’m sure mark will have no problem but I struggled with getting a smooth enough sealer coat. I also felt like the sealer coat was another opportunity to introduce trash….
I stopped using sealers years ago unless absolutely necessary and if I do it is a reduced primer surfacer I then sand lightly. Wet on wet sealers are more trouble than they are worth I have found and like you said more chances for a problem. @@shep145
Remember that you cant sand epoxy primer/sealer. Your sandpaper will gum up, thats why i dont uze it, i just put 2 or even 3 coats of 2k on. If you have dents, your still going to have to grind to do the body work( bondo) which is why i think its a waste as that stuff isnt cheap, dont know about the price where your at, but where i am its ridiculously expensive. Plus i see alot of supposed bodyshop stuff on youtube where, they put bondo on top of epoxy with out grinding it down to bare metal. All thats going to do is peel off like a banana peel
The paint rep specifically told me it sands well so we shall see and I will show it on the channel. The use of epoxy is to seal the bare steel and nothing does it better than epoxy at this time. Applying plastic body filler over bare steel is old school and since body filler is porous is absorbs moisture and if in direct contact with bare steel will promote rusting. The adhesion of body filler is dependent on the surface prep, not the material it is adhered to. If you think about it body filler is closer to the same base material as epoxy then steel and bonding similar materials is always best. I have painted close to a hundred vehicles in my life and ground off a lot of old body filler and have seen more failures bonded directly to bare steel than a painted surface. Your experience with it may be different than mine but I trust what I have learned through all these years. I will be applying fillers right over the epoxy as well after it has been prepped to keep the moisture barrier intact.

I think it depends on skill level. I used soooo much epoxy because it was my first paint job. I tried to use all epoxy and I would sand through to bare metal often. Also I struggled with smooth enough epoxy sealer coats. Epoxy time frames are sensitive too, the stuff gets absolutely rock hard. It came out ok but if I was doing it again as a first timer I would probably stick with a more traditional/simple route.
Agreed. Epoxy as a base sealer and then a Urethane is a good option. I will be testing the epoxy for sandability and clogging and decide from there. @@shep145
