  • Need help Folks !!

    Like my other question was asking where did the Orange color come from? But how about if I was to use a prime coat cured until flow then shoot the white until flow then my Fluorescent Yellow over that. I really do not want to strip this frame again !! I had 24 views on the other post and no replys need help on this one.. Have never seen or had this problem before..

      Get the frame to look correct

      The frame is going to be Fluorescent yellow as you see but as you can see also there are a few locations that an Orange color appeared not sure where they came from.. Now what is/will be the best way to handle the color bleed thru? Can I powder prime over this and then recoat White then Yellow ? or just start from scratch ?

          if it's me ,I'll strip it down and star again
          it you get to thick you'll lose strenght

          how did you cure it ? oven or lamp?
          something similar happend to me once and it was that the part was too close to the element .

            Part was cure in a 5'X4'.5"X8' Electric oven. The marks are no wheres near the elements 3- 5000 watt elements on the bottom. and the marks are all over it top middle and bottom. So not burn marks..
            Thanks..

              Hmmmm, thought I heard my name.
              First I see lots of light and dark spots, so address the coating thickness.
              Second can you explain your process in detail so I can understand better.
              This is multicoat, did you cure between?Whats your prep? I know this sounds redundant but I have to ask.

                Dale,
                Well I stopped the curing once I saw the marks.
                Ok :
                Used AirPlane Stripper to remove old black coating
                Then sandblasted clean
                Then dusted with air
                Then cleaned with Iron Phosphate Primer @90 Degree's
                Sprayed Bright White 1/2 cured @ 400 degree's ( I did not see the orange at this time but after looking at Photos I do see it in the white also)
                Let cool then sprayed the Fluorescent Yellow.
                Looked in Oven ( thru window) saw ORANGE Spots shut down oven and said What The (insert words here) ...
                Was going to do a second coat needed for the bare spots but wanted it to cool so I could flip it over ..

                  I don't see a prebake in your process?Is this correct?What does the frame go to?Also did you handle the part after cleaning?

                    Sorry forgot a step,
                    Once the frame was washed with the phosphate the frame was placed in the oven for until it reached 425 then cooled then white applied.
                    Yes the frame was handled after the bath but not with bare hands and very little just to hang for spraying, last time touched.
                    The frame is for a Go-Cart, I have about 15 more to do. Thank God they are not the same color.

                      I just reread the post again and it showed up on the white prior to second coat? Correct?
                      If this is the case then its a prep problem.I've had bike necks bleed oil outta the welds after prebaking 3 or 4 times.

                      I'm not saying its oil but something left on surface prior to coating. I would strip it and start from scratch.

                        I was kind of leaning towards that myself because most of the marks are lower on the frame and towards the rear of the cart ( by the motor). Would using a primer coat help ? Bummer that I have to strip the whole thing again... Thanks Dale..
                        BTW I'm leaving for vacation tomorrow night so if you reply to this I will not see it until next weekend when I return...

                          The primer coat won't help with this problem.It will more than likely bleed through that also. Strip it then prebake for a longer time and then reinspect for residue.You may need to prebake it a few times.Maybe you'll find the source of the problem.

                            Dale,
                            Well seems heat is not working or not long enough. 525Degrees 3 hours and all it's done is turn it brown and a few locations a Black and made it hard as nails.. Any ideas? I've placed it back in now and trying another 3 hours or so and see what that does..

                              Stain and Varnish remover or paint stripper.It'll take it right off or keep baking and try to go higher with temp.
