Anyone use any spray bomb etching primers?

BC · Feb 26, 2002

I realize after lurking here for quite a while that there are not many fans of spray bombs, but my question is in regards to the primers. I have some patch work to do one my cars and was wondering if these were a viable option for a small area to protect it for a while? Specifically, I saw that VHT makes an etching primer to cover bare metal and that's what I think I would need. Basically, I'm just starting on this body work stuff and need all the help I can get. I've been playing with my new welder and getting to the point where I want to try my first body patch panel. Basically, my question is what do I do after I get it welded up and ground down to protect it from rusting right away? Keep in mind, I will probably be doing a little at a time and this could take a while to get all done, so it might even be several months. My test car is also my daily driver ('70 Nova) so I will be driving it during this whole process.

Thanks for the help,
Sorry so long,

I'm no expert, but as of right now, anything out of a can is at least second rate when compared to a 2 part primer. I don't know if you are familiar with www.autobodystore.com, but they have an excellent message board on there...look around on there and ask your question...maybe even MARTINSR will reply

I have a little experiment taking place in my back yard that may give us an answer to this. I have used a number of different brands and found that they were nothing to brag about. They were better than nothing, but NOT a real etch. This one I am trying out is made by WURTH and is said to actually have acid in it. The can is a special plastic lined container and is suppost to be the real thing. I will post when I have some thing more to say on it.

I guess something I forgot to mention is that it doesn't have to be a permanent solution, just provide some protection while I'm driving it until I get to where I am ready to strip everything down and do the real thing and paint.

Does that make any difference?

Thanks,

If you plan on just making temporary repairs, I would say go ahead and just use primer. Understand that primer will absorb moisture. But for the real thing, don't was a spray bomb. My old boss, when I worked for a body shop, informed me that bombs have silicone in them and that is the worst enemy in a body shop. It will cause contamination to the paint. When time comes for you to do the real work, make sure you clean the body with degreaser, before you do any paint, in that area.
