Liquid Coating
White Polyester Melting Disk
I am curious if you know of a prefabricated low-temp melting polyester disk (1.5-inch diameter or so) that I could lay down on the top of the hot disk to bond to the clear polyester to create the nice plastic backing.

There is an institute (Name Withheld) that will teach painting, custom painting, etc, but you must also sign up for their auto collision and refinishing course. Unfortunately, I learned that these courses would cost me $28,000 as quoted to me by the institute representative. I thought that was FAR too high, and will pursue your advised method of practicing and learning by trial and error, picking up pointers from people I meet, or technical books you can buy at the painter supply shops.
Read MoreDip Tank Equipment
My company is purchasing machined and painted lifting hooks from a third party manufacturer and wish to move these processes in-house. The dipping process seems to work well but I am having a hard time finding a company that makes this type of small-part, low-volume equipment. Do you have any suggestions?
Read MoreBleeding-Out Issue
There is a copper band on the outside circumference on the part which does not require painting so it is covered during paint process. We see very slight bleed-out from under this band after 2–3 days.

Our inquiry is about whether we should install an automatic spray coating system for applying a shop primer in our structural steel fabrication facility. This system needs to be able to coat sheet metal and structural profiles in different shapes like I, U and so on. Is automatic coating a satisfactory method to paint these parts or shall we coat them manually?

Painting Large Steel Tanks
We are seeking advice on automating the painting booth. We have turntables to turn the tanks and now plan to automate the process with automatic gun heads. Our initial thought is to use automatic heads with high-volume pumps. We currently use an industrial enamel but would consider newer coatings and processes if they are applicable. Could you provide some practical advice before we start purchasing equipment and planning our production flow?
Read MoreSolvent Wiping
I must take issue with your reply to B. L. in the February 2006 issue. Although there is no doubt that he needs to stop using toluene for hand wipe cleaning due to its toxicity and flammability, there are a number of perfectly acceptable alternatives.
Read MoreCoating Military Medals
Will the heat of curing them (around 400°F, I understand) damage or discolor them? Most of the badges are brass or silver (some with soldered fittings on the back) and several of the medals are bronze. I know that the heat of soldering brass will usually discolor the brass, but would the heat of a powder coating oven be sufficient to melt the solder or discolor the metals?
Read MorePainting Stainless Steel Flexible Tubing
I am looking for a method to paint stainless steel flexible tubing for gas and water lines. We have made a few attempts to paint them, however, since the tubing is flexible stainless steel, every time we bend it, it makes a cracking noise, which is most likely the paint cracking from the bending. What methods/processes are there to have this not occur, and what paint is necessary?
