Cold Oven vs Hot Oven

Just wanted to get an idea of what you guys are preheating your oven to prior to entering the parts in the oven. I notice, sometimes, usually smaller parts, or less dense parts i should say will flow out nicer compared to thicker parts (say car rims). So my question is, how hot is your oven when you...

Super chrome

Super chrome is back from prismatic.

Just finished a set of wheels with it. Came out with excessive orange peel.

Do you typically apply these chromes on the heavy side or the ligher side?

Re: Painting over powder coat

Thanks duke for the reply. Yeah, we usually use, "scuff stuff" with a grey pad to scuff the wheel down. Never had any issues like that, but, the areas that are hard to reach, after 6 months or so, i notice it flaking off (usually less than 1mm in that specific area) So was hopping that an adhesion p...

Painting over powder coat

Just wanted to clarify something here, and probably duke might be the best person to answer this. Do wheels here, and sometimes when 1 of the 4 come in, we have to paint it to match the rest. Regular procedure, use a grey glossy polyester powder, full cure it. Scuff it down, then shoot and clear (li...

Re: Overcure

I guess we'll have to wait and see if this piece every comes back down.

I hate stripping RO primer. I think its worse than the German wheels' primers.

Overcure

So I finished hot flocking some red oxide primer for some outgas issues @ 430F, and put it back in the oven and @ 450F to fully cure it. However, i forgot to turn on the timer, and came back after 2 hours and the oven was still running @ 450F... pulled out...it looks okay, but should I be afraid of ...

Re: Cleariest clear coat

Yeah. I figured acrylic clear would be the best. And the thinner the better (for everything, peeling, flaking, cracking etc.)

But at the same time im sure there are ones better than others (in acrylic).

Cleariest clear coat

Any recommendations on the best clear coat to purchase that has the best clarity etc.? Im looking to buy a full box if this is successful. I'll be applying it over polished aluminum, and chrome plated parts. Don't ask me about the latter, but the customer is insisting. I've shot Akzo Nobel's acrylic...

Re: Matching issues

I know in the automotive painting world, plastics and metal substrates give slightly different colors.

Could be the case in this too, but I highly doubt it. In that case spray a "base coat" say a smooth silver then the triple bronze. That might help.

Or the ramp up.

Re: Matching issues

Maybe ramp up speed of the oven is too fast for the small caps as opposed to a big wheel?
