To All,

I am getting prepped to re-paint the windshield (including the A pillars), rear window, and rocker panel chrome trim. It had been painted a satin black before, but it's in bad shape now and adhesion was not great. I feel a satin black goes best with my cars current paint color. I have a general idea about painting and prepping and some experience, but I thought I should ask everyone first to see if anyone has any personal experience, tips, dos and don'ts before I begin. I was thinking a single stage, easier to repair later. I can see the chrome was never sanded before, that might explain the bad adhesion, or they might have used a rattle can! I tried searching the forums, but came up empty. Of course you have to ask the right questions!

Thanks!!

I would think an epoxy primer over a well sanded chrome would provide a good base for the topcoat.

There's something called adhesion promoter specifically for use on chrome prior to painting. Also recommend using Prep-Sol to remove wax, grease, silicone, etc.

Thanks! I can see this chrome was never really scuffed up. Doubtful the paint had any surface to grab a hold of. I will prep this well.

I will check that out. I have used plastic adhesion sprays before, haven’t seen chrome. Definitely will clean it well. Prep solv or Pre from Eastwood. I also find washing everything with dish soap to start hells too. Seems even solvents have issues with some types of oils/dirts.

Thank!

The problem with alcohol as a cleaning solvent unless you're spraying it on is that it uniformly dilutes the contamination and evenly spreads it around the entire surface.🤔

Excellent Point. Body guys never use alchol for prep work. It can introduce some of its own issues. Spraying, as you mentioned, is the best way as well (with prep solv or equivalents), flood the service and use a clean lint free rag, wipe in one direction and turn the rag to a clean side. Don't go back and forth and don't reuse the same part of the rag again. Of course, this method is for the final wipe down before applying paint or other top coats. I was lucky enough to have learned those lessons before I painted. Fish eyes, bad adhesion, and other defects show up and ruin your day. Even your fingers or hands are bad for the surface...gloves, which wearing while painting or cleaning should be a must. Ha, the only problem I had with gloves have been getting too hot, sweating, and having sweat drip out of the glove when my hands were vertical. Watch out for that...another bad day for your paint!

Thanks again gents. Looking forward to getting this trim looking great again.

I used 3M 3 inch wrap on my 78 SA rocker panels. It looks better than paint and doesn't chip or fad.
