Duracoat How necasary is the phosfo?

[Shawnba67]

I see that lauer seems to recommend their duraphos on bare metal first but is it really necessary for an ok job?(read done by me for me) i also plan on useing my belt sander instead of oxide blasting if I can get away with it. Any one experienced with this on the cheap type plan?

Being a product that anyone can buy and apply, you should probably expect to hear different views. That said, it matters a lot. A good analogy would be painting a car without primer. I've done a fair amount of work with it and will state unequivocally, that it's a good product IF proper prep is done before application. All else being equal except the Park step, it's night and day different, in terms of how well it holds up. It needs a course sand blast and parkerized for best performance. One caveat is that it adheres to most polymers well, obviously without the same prep. There is more to adhesion than just mechanical adhesion.
IMO, they would do well in the long run if they required certification to purchase.

I would not apply without al oxide blasting. Not being a smart ass here but if you arent going to do the proper prep just consider a good degrease and krylon rattle can job. If it scratches or chips touch up is easy. If you decide to change colors just soak in acetone and recoat. I dont think Id spring $ for the duracoat and then not use it as directed, I dont think the results will be satisfactory

I understand what your saying, I work for Chrysler I have seen first hand how a company can recomend all sorts of things that arent necessarily any real benifit to the job ust to cover their own arse.
So i guess im saying your say not the proper prep, Im asking how you know they arent over recomending, while trying to temper that with the fact that they make it and ought to know what it takes. But ive seen first hand l overkill instructions from the manufacturer before.

Also how would blasting be significantly better than sanding? Serious question here

Secondary quest I cannot find any instructions for the duraphos or its application process anyone have these or the laymans terms on how to do it? thanks

Duracoat states in the directions that it's OK to sand the surface for prep if you don't have access to an aluminum oxide blaster. I use this method on many of the items I duracoat and have not had any trouble at all. The important thing to remember is make sure you give the part enough time to cure before you put it into regular use. The directions state 4 weeks cure time.
