Eastwood Self Etching Weld thru Primer 454grams Aerosol - EW12899Z

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.

★★★★
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.

Great for years!

I have been using this pre-weld primer for years. Have great confidence in it.
★★★★★
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.
I recommend this product.

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!)

WOW

I do a lot of restoration work on old Jeeps and use this paint exclusivly for protecting my work on the bayer metal even if I dont weld it. I buy it by the case.
★★★★★
easy to use

Works 100% better then the copper base one they sold before...this one is high quality and works and doesn't clog up at the nozzle

FAQ

(Qu) After applying the weld thru primer is it necessary to weld immediately after the primer has dried or does the primer remain effective if I have to wait until the next day to complete welding?
(An) You can wait until the next day if the vehicle is kept indoors.
(Qu) is this product compatible with 316 grade stainless steel?
(An) This could technically be applied to properly scuffed stainless steel. However we would not recommend welding through this since it would give you contamination that you should not have on stainless.
(Qu) Is this compatible with epoxy primer? Can I spray it over the top.
(An) This product is not compatible with Epoxy primer.
(Qu) How long do you have before you have to scuff or recoat with added  primer before topcoating
