Basic products/paints for starting rust repairs

[NickF]

Sorry Ryan I may be getting out of my depth regards epoxy

You could ask your dad about old school primers

Epoxy is more resistant to absorbing moisture

Yep, and stopping any form of H2O getting onto steel is critical for long term rust protection - so, IMHO, the Fe/Zn Phosphate treatment followed up with a hard, non porous layer of epoxy would be best.

I can just see Lauchlan/Locky/CAF sitting back with his bucket of pop corn with a massive grin across his face as this discussion develops. 

Just to add to the mix this link provides some further insight into urethane primers: https://www.autobodysupply.net/Articles.asp?ID=139

My advice, right or wrong, was that using etch, followed by acrylic urethane primer when applying a clear over base finish was the best approach. 

There is more than one way to skin this cat and it all comes down to choosing a method and applying the associated advice and rules. 

Now where's my pop corn?

There's no 'U' in my name, you sandgroper. 

BTW all, if you perform a search, this has all be covered before...

Lol me too. I know gav and Lurch are in the epoxy primer camp as most their recommendations on the forum have been for epoxy. 

Evidence: exhibit A

this thread wasn’t meant to devolve into an etch vs epoxy war lol 

just wanted to know what specific products people used for each “job/phase” involved in rust repair/panel prep and their experience with said product. As there are so many different brands/products it’s enough to make your head spin! 

@C.A.F. Lurch, forum searches bring up results but they are scattered and often conflicting. Would it not be valuable to the forum for a sticky to be created for the bodywork section regarding best practice products and their use? 

I know you’re busy restoring z’s and takin names. But you would probably be the best person to do a write up, being the resident subject matter expert. Even just the exact products you use for each job and any important side notes on using the product? Though you may not want to release all your special tricks and secrets to the world....

there is sirpents sticky which is useful but incomplete. He also advocates for the use of polyester which from my research is unusual as a base bare metal coating.

Found this page which I thought was a good read

There's no 'secrets' young Padawan - just new technology in products and equipment, along with new procedures to complement them.
I'm fortunate as my spray painter is a master of his trade and is always at the forefront.
Furthermore, everything that we do can be done by oneself at home in oneself's shed/garage - it's not inaccessible to those outside the trade.

I'll consider writing a post about how I go about painting a classic car...

From the OP's initial post there are in fact two parallel threads to all this robust discussion.

Firstly, what products are best used, or avoided, as part of the metal surface preparations prior to laying down fresh paint.

And secondly, what products are best used to treat / neutralize (maybe remove) and then seal over rust identified as present in cavities - such as chassis rails - that can't be accessed.

Interesting. Keep it coming.
