Just finished blasting the frame for my '46, it only took 12 years, 2 moves, 3 kids and a pandemic, but whose counting.
Now what do you all recommend for cleaning before primer and paint. I have read and researched, mineral spirits, paint thinner, prepsol, and even soap and water. It will be difficult to get the spirits, thinners and such into all the areas then wipe them back out to clean up the metal. Soap and water sounds like flash rust to me. What have you done to get the metal ready for primer after all of the sanding and blasting?
Do you recommend epoxy or self etching primer?
Information, experience and expertise is always greatly appreciated.

"it's only old if you can't find a use for it; otherwise it's cool and i'll use it."
I may get some flak for suggesting this, but you could blow out the areas you can't reach to wipe down then, use a spray bottle with grease and wax remover in those spots and then use your air blowgun again to dry the grease and wax remover out. I'm assuming it's freshly blasted, so your main issue is getting the media and dust out.

Kevin, Thanks. I have already done the blowout. My question is more about surface cleaning and preparation. What products do or have people used/recommend to get ready for their primer? And what primer, self etch, epoxy, or both do they like to use to get ready for the paint.

I recommend a spray with phosphoric acid and wipe down with paper towels while it is still wet. If it drys before the wipe down, rewet it then wipe down. I like Master Series Silver for a primer. It was originally designed as a bridge primer. Master Series totally seals the metal and is better than other products on the market. Check You Tube for a comparison.

I've wiped things down with brakleen in the past. This time around, I've picked up some Final Wipe. I had been using SPI for my epoxy primer, but for the current job Tamco Paint In fact, my crew cab repaint is going to be Tamco from the ground up. OEM color. What really sold me is the customer service/support! Completely outstanding!!
BTW, etching primers and epoxy primers do not get along!!
If you use Ospho like products, the results become the base on which you put your primer. Primer manufacturers usually want bare metal with a certain scratch depth (mechanical bonding) to bond their primer to the metal. Ospho like products don’t provide that.
