How long will DP90LF hold up

Title says it all. Reason I ask is that I just got the grill media blasted and they sprayed it with DP90LF. If it will hold for lets say 6-8 months I may just hold off on taking the parts to the body shop until I can get the hood, passenger side fender, & cowl down there as well.

I`d say it should hold up that long fine.Will the stuff be outside?I`ve only seen rust start through after blasting when I know that moisture got to the metal before it got a coat on.

Re: How long will DP90LF hold up

I applied mine over a year ago as a primer/sealer and it's held up very well - no chalking. Only learning curve (as a new guy) was ensuring coverage (I have a few thin spots :() and applying seam sealer, etc. as if it was a full paint job.

If it was mixed just as a primer, then it's completely permeable and you'll be seeing rust spots in a month or so :(
