I tried the Eastwood kit on some suspension parts a while back. The results were ok but nothing to rave about. We ended up using an acrylic urethane paint on the remainder of the parts as it was much easier to use and the results were just as good. Remember you must heat the parts to 400 degrees in order for the powder coat to flow out. Unless you have a good IR lamp set up or an old electric oven, not the one in your house,it's not worth trying.
I have never done it myself, but i have had it done at a local place and i must say it is awesome stuff.I would inquire what the film build is onwhat ever product you eventually end up using.I am not sure what the part your asking about looks like but if glass must slide through it during installation, and the film build is to great you have just waisted your money.
I do powder coating with the eastwood products and I even built a large oven out of an old chest freezer using a garage sale electric oven. I have been satisfied with the results but it doesnt appear to be anything to get rich off of. By the time you sandblast and coat the time involved is too costly. Cant re-coup it all on coating fees. But for the hobbyist with some extra money and ambition, its worth the investment.
You are better off taking it to a powder coater, unless you do a good job of pretreatment and have a consistant temp in your oven and don't underbake or overbake it. And there are very good powders that will withstand UV resistance like Urethanes or Polyesters.
I am a major power user of powder coating if yoou have read my previous posts on the subject. Have done many frames and engines and wouldn't consider anythig else, including catalyzed urethane paint.
As nosliw721 and others have said, it is a difficult process to do as a hobby. Not only do you need specialized equipment like a big oven and sprayers but you can't afford to keep abreast of changes in powder materials or stock everything you need. There is a shelf life to the powder.
I am a hard core do-it-yourselfer, even cast my own Chevy straight 6-cylinder manifold, but for powder coating, I defer to the pros. I look at it in the same vein as chrome plating. Sure ai could do it myself but why? Can't save any money doing it myself and I would do it so rarely that quality would suffer. Cost from a shop is not much more than it would be for a pro sand blast job on your frame and you get a great finish with the latest material technology.
Phat - LOVE the look of your engine compartment! Hope my 235 comes out that nice.
One thing about sandblasting before powdercoating. DO NOT use silicone or silica sand. You will have problems powdercoating over it as it will leave a residue. Use an aluminum oxide media to blast with. You will get much better results.
