OK

Hey, willys. I will have to try so of that. We are stripping a 46 PU to frame and that should come in handy. It will be a few months away, but maybe I will remember to post a remark or two about it. Have you ever used it? Just spread it on and sand smooth? Let the PC cure it? I don't have an oven, so hope it works that way. You are always a book of knowledge.

No haven't used it myself, I just became aware of it within the past couple of weeks. However, the description sure sounds like it is miracle bondo and it was developed in the first place for the powder coater industry so I am pretty sure they will cure it for you during their treatment. The product specs say it cures @ 475F for 1hr which is right where the PC treatment is done.

Just talked to my powder coater and asked him about Lab Metal. he said they have used it and it works great. They even used it to build up door sills that were not going to be powder coated on a hot rod project where welding or regular bondo was impractical.

Tips he gave were -

- Do your sanding and finishing soon after it sets up because when it has cured very long it is as hard as steel!

- Apply it in thin layers and let it dry well between. If applied too thick and not allowed to evaporate the solvents, when powder coated there will be a rim of pinholes in the final finish around the feathered area where the trapped solvents out-gas.

He also mentioned that you can use slow cure JB Weld under powder coating, but it is pretty runny and hard to work compared to Lab Metal.

I erase my PMs as soon as I act on them to keep the directory open - fills up pretty fast and is of limited size.

Lab Metal is similar to bondo in function but different in chemistry. It doesn't use a catalyst like 2-part bondo does. It hardens by evaporation of solvents only.

I'm 'expert' in powder coating like I am 'expert' in roc 'n roll music - great audience material!! Not sure what would do that but since the coating is the same plastic all the way through and the stain you describe sounds like a superficial surface blemish, can you just polish it out? What does your vendor say about it?

Power Coating Primer



Powder Coating Primers are needed for adhesion problems, uneven surface quality and orange peel look. Their are two major type of powder coating primers normal and out-gas stopping primer. Out gas primer is best used on aluminum and cast metal parts as micro cracks in cast metal hold gas and impurity's.

So yes use powder coating primers when high strength is needed or when you have adhesion problems.
