Eastwood Self Etching Weld Thru Primer 16.1Oz. Aerosol Can

Product Description

Eastwood 16.1 Ounce Aerosol Can of Self Etching Weld Thru Primer.

Eastwood's Self Etching Weld Thru Primer combines the benefits of a weld-thru and the capabilities of a traditional Self Etch Primer. This unique formula has organic binders that replace conductive heavy metals such as copper and zinc. These organic binders will burn off during the welding process leaving a corrosion resistant etching primer.

This product will reduce spatter and distortion caused by excessive heat that occurs during the welding process. Compatible with MIG, TIG and Arc welding. The etching primer will enhance adhesion and durability and is compatible with most top coats.

*Apply 2 medium wet coats, allowing 5 minutes flash time between coats.
*Allow to cure at least 20 minutes prior to welding.

Eastwood Self Etching Weld Thru Primer 16.1Oz. Aerosol Can is rated 4.5 out of 5 by 5211.
Rated 4 out of 5 by from Does the job It seemed to work as claimed. Had no welding issues. Only burned off at the welded areas and did not burn too far back. My only complaint was that the paint would spit as I was spraying larger areas. I don't know if the spray nozzle is not designed correctly as paint would build up on the nozzle and then eventually get into the spray stream which was the cause of the spitting. Not a big deal as the paint will get a topcoat, but this needs to be addressed or looked into. So it gets 4 out of 5 stars due to this.

Rated 4 out of 5 by from Great Product--for a price Works exactly as intended. Make sure to shake well before using and there will be no problem with not having enough propellant. Get this stuff when it's on sale.

Rated 3 out of 5 by from Better than nothing Great for getting in areas that get sealed up/overlapped and cant get top coated. It does add to the resistance of the weld, so you'll need a little more voltage. comes right off when you wire brush the slag afterwards though... Also, "self etching" paint is said to conflict with magnetic paints, like Monstaliner. so dont use this if you plan to use magnetic paints....

Rated 5 out of 5 by from great product I have used other Eastwood products with great success and decided to try this one. This paint is great! I have used the weld-thru primer for the backside of patches prior to welding and was very pleased with the results. I would like to see Eastwood make smaller sized spray cans to get into hard to reach places.

Rated 5 out of 5 by from SELF-ETCHING WELD-THRU IS GREAT! How many times have I welded a rocker closed or sealed up a pillar wishing I had the maximum possible primer on the inside, so I don't have to do the job again?!? This primer is great! Just spray your parts and keep working, since the factory never even put paint in there, it's gonna be a looong time before someone thinks they have to revisit my work! (Probably never! HA!)

Rated 4 out of 5 by from Weld-Thru Works I purchased Weld-Thru just to give it a try. Sprays on nice and smooth, dries fast and covers well. Great for plug welding two panels together. I tried it first by cleaning off the primer just in the area of the plugs on a test piece, then without removing any primer. Works good ether way. Good product..

Rated 1 out of 5 by from Lids popped off - 4 Qts gone I bought 4 quarts and it was in the car in the box. Had to go to work for a few months and when I got back to prime and to weld the roof skin and floors in - the lids had popped off or loose and all dried up. Didn't even get to try it. I want my money back - I'll ship the cans back.

will this work with electrical connections?

It's not really meant to be in contact with electrical connectors. Mask that area off.
