I am now on my 3rd valve cover because I keep getting terrible results with Caswell Super Chrome. I guess I'm doing something wrong but I dont know what. The piece is cast aluminum. My exact procedure this time was-
-sandblast piece
-clean off with nozzle then wipe down with alcohol
-outgas for 30 minutes @ 450-475 degrees
-i didnt like how clean it looked so i blasted it some more just to make sure it was perfect
-sprayed with aire and wiped down again
-placed in oven for approximately 10 minutes at 450 degrees or so
-take out of oven, let cool for a couple minutes then spray with super chrome
-place in oven for 20 minutess @ 380 degrees after 15 minutes i saw the finish was **** and shut the oven off. This is the pic
The first time I got this finish I thought maybe I picked something in the air but I really doubt thats the case. This is the second time this has happened and both times its with Super Chrome. I got my rear valve cover to come out good cleared it and its all good but I NEED this front one to turn out for a show next Fri.
Also when I get a crappy finish like this what can I do? Sand it down and respray? How well do the strippers made for PC work? Any help would be greatly appreciated.
