Tell me more about where you use the mastercraft silver primer. Do you do the metal prep as they recommend before application? Roll or spray?
We use the Master Series on floors usually.....I've used it on a few frame parts too and or brackets that need a little love. I like it because it will stick to new metal, old metal, paint, rust, etc. It's very simple stuff. I have never used their metal prep solution. We've never had adhesion issues once it goes on.
We always brush or roll it. It's pretty potent smelling stuff....would not want to spray it outside of a booth.
The guy who owns the place that sells it is great to talk to....a wealth of info.
No idea if this is true or not but it must be because I read it on the internet
...this was what POR15 used to be back in the day. A heavy aluminum based sealant for rust. Apparently car people didn't care for the silver coating so POR15 altered their formula and turned it black...but the change in formula resulted in a product that wasn't quite the same. I think the guy at the company said that this is what they use on bridges....it permanently cuts off oxygen to the metal, stopping rust. Very effective stuff.
We did my floor in my LV with it....the guy told me to use fiberglass fibers in the material to help fill in pinholes or holes in the floor( this stuff is popular in the VW community). We did that on the LV and it filled up every pinhole. We filled up some stuff that was bigger than pinholes too. That floor is solid as solid can be with this, sound deadener and then bed liner.
Get a couple of quarts to play around with...well worth having it around. Just make sure you really store it tightly sealed. I either use a new metal can for it or the old saran wrap trick between the lid and the can. I try to use it out of cups, never out of the can either. Cures fast in humidity.
When we topcoat next weak, I'll give it a light scuff(you do not want to scuff down thru the aluminum) and then start the bedliner or sound deadener process.
I think the VW guys use it for the insides of bumpers or something.....maybe tail light housings. Can't recall where I read that.
