Sand Blasting and Painting Implements and Trailers

Here's what I use and never had a problem with paint failing. Rust Inhibiting Coating SKYCO OSPHO 1 Gallon - Whitehead Industrial Hardware

OSPHO is the BEST !!!!
I have been using it on steel for MANY years, under all sorts of top coatings.
That price at $24.99 per gallon, is excellent also.

No longer recommended to use an etch primer under an epoxy primer:

Did you know? It is no longer recommended to use an etch primer under an epoxy primer. Residual acid from the etch primer can interfere with the proper curing of the epoxy. This may lead to extended dry times, potential blistering, and even adhesion failure. So next time you are planning to paint bare metal with an epoxy, follow the recommendations on the psheet and use the epoxy directly on the properly cleaned and sanded bare metal substrate.

NEVER use SPI Epoxy over Acid Etch/Wash Primers or Rust Converters. It will
not work and we strongly suggest if you want to use a rust converter that you use
the rust converters paint system instead of SPI.
Acid treatments should not be used unless you know the proper way to neutralize
them, again call us first to be safe. Acid films can cause an adhesion loss.

In the decades I have been using these products, it is certainly not the first time I saw them change a recommendation that works well.

When you talk to the the engineers involved, and, I did a lot of that, it's always been the same thing, the problems occurred due to improper use. Over application, under application, improper mixing ratio, etc.

If they make the product so it is DTM, direct to metal, (few are), adding another etch, is unnecessary, and could also potentially be causing problems.

I have seen countless primer adhesion issues over the years. So, I will continue to use wash primer, as I have without any issues since the 70's, unless it's not recommended for the specific product I am using, and I have not used it successfully in the past, with those specific products.

Went back to Nashville today, inspected, paid for it and left with the trailer and a big smile on my face. Quite frankly, I was amazed at what this crew did. Sand blasted the whole trailer (top, sides and belly), applied a two part primer that bonds with the metal and then painted the entire trailer the off white (almond) color, also a two part paint. Did the same with the wheels, all six of them. Still have to apply some DOT reflective tape but, this was one heck of a Christmas Special they ran and I am very pleased with the results.

A big :thumbsup: to:

I highly recommend their work based on my experience with them.

pics!?!

Attempted to email you the pics I have. If you don't get them, let me know. Some are of the in progress work and a few of the finished trailer.
But, all were taken in bad lighting, will try to get some decent pics tomorrow in the light of day. Still need to apply that DOT reflective tape and looking at adding some additional LED lights.

Got them... wow!!! Nice and it looks like they did a thorough job on the blasting. That will look absolutely great once you get it properly decal'd and LEDs. Although the bone color was not my first choice I think it works. :thumbsup:

Yeah, the almond wasn't my first choice either but, of the options available for the quoted price, it worked me for.
Honestly, I'm amazed at the end results. Glad I hopped on that Christmas Special they offered.

Why does he get pictures and we don't? Hint Hint.

That turn around was quick. I would have guessed they would have it for a month or so.
