Hey guys,

Follow up question to my temporary paint question…

So let’s pretend I plasti dipped my car. Then I decide to peel the plasti dip off one of the fenders and prime it (after sanding and prepping first). Maybe a couple weeks after that I’d do the next one.

What kind of primer would last for a few months or even a year on a garage kept car? Would a can of that primer have a good shelf life or would I need to buy it in small quantities? And what kind of paint would be most compatible with that primer?

Thanks in advance,

Steve

I’m on the same journey as you. Car down to bare metal but have to contend with flash rust as I repair rust one panel at a time. I don’t have the ability to spray paint in my home due to EPA/local pollution rules.

My solution is just use epoxy primer (2part) and roll it on with a disposable foam roller. You can mix up small quantities using a graduated cylinder (like you used in chemistry class) to get the correct ratio. Put the rest on the shelf. Unmixed it should last a year or so if you seal it back up. Mixed paint left over is a throw away as are the rollers. Of course you want to prepare the surface using Ospho or rust converter but ensure you wash the residual off and dry with a heat gun before painting. Some epoxies don’t like the acid left in the surface.

Yes it’s a bitch to sand and you don’t get a spray finish without sanding but it protects the metal for a long time. If you work at it you can sand it smooth and is the perfect base for the next paint step. Wait until the epoxy has well and truly cured (a couple of weeks) before trying to sand otherwise your sandpaper will clog up.

I’m using it on the inside in particular without worrying about sanding as nearly all is going to be covered up with headlining or carpet.

When doing repairs to an already painted surface you just scuff and reapply the epoxy.

Eastwood have the roll on epoxy. It might be worth spending the money to get it. I can’t get it cheaply enough here and just use something that says it can be brush or roller applied.

What I have had great success with in keeping some parts from rusting is this!

Get some stretch wrap from a big box store. This is the stuff they wrap around pallets to stop the load from falling off. It comes in rolls about a couple of feet wide. Prepare your doors, fenders etc then spray with WD40. Then wrap several layers of the stretch wrap all over the articles to seal it. I have parts stored like this for over 2 years with NO rust. You can even drape it over the body if you can manage the curves etc. As long as the plastic is in contact with the metal it will remain dust free and clean. Make sure all the surface is covered.

Whilst I haven’t tried it, using shrink wrap (same stuff but you use a heat gun to shrink the plastic on and to the exact shape) may work as well but is much more expensive. It’s the stuff you often see on new appliance packaging to protect and hold it tight to the foam packaging.

When you are ready to paint, wash the surface with some solvent, alcohol, thinners to remove the WD40. WD40 does NOT contain silicone which causes fish eyes in painted surfaces.

Get a 2k epoxy primer. You can get Spray Max or a Car-Rep 2k in an aerosol (make sure you wear the proper breathing and safety equipment):

Thanks for your replies. I’ve been doing my own research and I do believe Apoxy primer is the answer to my question. The spray can idea and the roll-on idea sound like good solutions that I need to cost out. I had an idea of taking six concrete blocks, standing 8 foot long two by fours in them, and then filling them with concrete to create wooden poles that I could staple plastic sheeting to to make a portable painting booth that I could use in my driveway. Maybe even use a fan to create a gentle air flow out of this makeshift booth.

My thought is I’m going to remove the paint from each section completely and then use epoxy primer. I have recently learned you can even tint it different colors.

Yes 2k epoxy from the spray can. Yes use PPE. I didn't because I'm stupid.

If you go to the trouble of using epoxy, don’t cheap out. Use SPI epoxy. It lays better and smoother, and doesn’t gum up like every other epoxy when you sand it. Sikkens / PPG/ Shopline all sand like peanut butter.
The 2x4 idea works on a still day. Use 5 gallon buckets instead of blocks, the handle will help.
