Eastwood Gray Self-Etch Primer Quart is rated 3.727272727272727 out of 5 by 22.
Rated 4 out of 5 by from Nice, but plan ahead! This aerosol is easy to use, and does lay down nice and smooth, but being a single-stage laquer-based primer, it's pretty soft, and lifts easily with acetone based cleaners and topcoats (don't use the Eastwood LOW VOC PREP cleaner on this stuff, as the primer will come right off). Regular PREP is fine as it is Xylene based. I laid down this stuff, then the low VOC primer, then Featherfill G2, then thinned low VOC primer, then topcoat. In hind-sight I probably could have simply started with the low VOC primer, and done without the self-etching stuff, but I was working on the car in sections over 3 years.

Rated 3 out of 5 by from Good primer, bad delivery I have been using the self edge primer quite a bit as well as the weld through with good results. That is until the last purchase. The new labeled primer has a different head and does not spray well. Had to toss the last can half through due to the head blocking and uneven spray pattern. That said using an acetone prep and finding a spray head that works the primer holds well as temporary covering over fresh metal until it can be repainted as one piece.

Rated 2 out of 5 by from Fed up with Eastwood aerosols I have about had my fill of Eastwood aerosol sprays dropping spots in addition to the spray. I've had this happen with multiple cans of their self-etching primers and even with the 2K urethane primers. I've seen Eastwood's responses blaming a clogged spray head but I have had this happen from the first spray to the end. I could never use their primer without expecting to sand out these droplets. It is rare for this to happen with other manufacturers so I really wonder why it happens with Eastwood products.

Rated 1 out of 5 by from Below average performance I bought a gallon to spray my aluminum dog trailer I just got done building. After coating, I covered it with primer sealer. Then top coated with PPG urethane paint. After running through miles of loose gravel, I picked up few rock chips. They were right down to bare aluminum and you could not see any trace of the etching primer. In fact I could peel small pieces of paint off right down to aluminum. Apparently it did not etch into the aluminum at all. The aluminum was scuffed and cleaned with wax and grease remover prior to priming It's nothing like zinc chromate that was legal to use years ago. Next time, I'll spend a little more money and buy a 2-part etching primer from an auto paint shop. They have a higher acid content so they will etch better. I'm disappointed with this product.

Rated 5 out of 5 by from very good product I have used this primer on several jobs, coke machine, model A 1931. Adheres good to all clean surfaces and works with all over coat paint except epoxy primer or eastwoods chassis black. Use thin coats till surface is covered. Paint over primer soon after dried. This is not a sealing primer so care must be taken not to expose to humid damp air. primer absorbes paint as well as dampness if allowed.

Rated 4 out of 5 by from Good product I found the self etching primer easy to use and it had very good coverage.My only complaint would have to be with the spray nozzle, after spraying for a few minutes it tended to drip paint and you had to be careful not to let it drip on a surface you werent; working on yet, or a surface that was already painted!

Rated 4 out of 5 by from Good product I was very pleased with the self-etching primer, good coverage and dry time. About the only complaint I have is with the spray nozzle, it tended to drip paint after spraying for a few minutes. I had to be real careful what was underneath where I was spraying!

Rated 5 out of 5 by from Great product Works great for those small jobs. For the bigger ones it's a good way to protect your work and allows you to move on to the next area. When all finished, all you have to do is sand smooth and continue on with the finishing process.

Can i paint over this primer with the eastwood ceramic engine paint with hardner?

Asked by: Thom K
The engine paint does not require a primer. This primer would not be able to handle the engine temperatures.

I just primed a galvanized steel hood with this, but won't be able to paint it for about a month. Is it ok to leave the hood outside with the primer on it, should I put a tarp over it? Also, will I need to sand down the primer when I paint the base?

Asked by: snelan
I would cover it because the primer doesn't have any protective coatings so it could damage it. Kind of like base coat it needs uv protectantt

I have some aluminum to paint, I am going to use your self-etching primer. Could I use an enamel top coat over the self-etching primer?

Asked by: TW2014
That's dependent on your specific top coat. If it's compatible with self-etching primer, there will be no issues on the side of the Eastwood primer.

Back working on my old Dodge pickup. Before I stopped, 1 year ago  wiped all the bare metal down with After Blast,metal prep. I now have some flash rust on the metal. Should I reapply or can I scuff off the loose rust than apply your Self etching primer 

Asked by: rtse440
You will want to remove the flash rust and I would reapply the After Blast after cleaning off the rust. Once cleaned, you can apply the primer of your choice. I prefer to seal the metal with our direct to metal Epoxy Primers.

Can this product be used on filler materials such as USC AG47 and Bondo?

Asked by: Miner
Self Etch Primer is intended to be applied to bare metal. If you are looking to coat bare metal and filler, I would use our Eastwood Epoxy Primer.
