Eastwood Self-Etching Weld-Thru Primer 16oz Aerosol is rated 3.6957 out of 5 by 23.
Rated 4 out of 5 by from Welds great but hard to spray the last third I bought this for welding in new floor pans and patch panels on my Nova. Works great and sprays good for most of the can. When the can got low its almost like there wasn't enough propellent and it started to spit and sputter. Welds great, doesn't seem to bother the welder and doesn't burn too much. I ordered more.

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 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.

How long do you have before you have to scuff or recoat with added  primer before topcoating

Asked by: Jack R
Allow this to dry roughly 30 minutes before scuffing and applying your topcoat.

Eastwood Self-Etching Weld-Thru Primer 16oz Aerosol

Item #12899Z Brand: Eastwood

Combines benefits of a weld-thru and traditional self-etch primer

Details

Eastwood's Self-Etching Weld-Thru Primer combines the benefits of a weld-thru and the capabilities of a traditional self-etching primer.

  • Enhances adhesion and durability of top coats
  • Prevents corrosion and reduces spatter
  • Non-conductive organic binders
  • Gray color

This unique self-etching primer 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 self-etching primer for paint prep. 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 metal-etching primer will enhance adhesion and durability and is compatible with most top coats.
