My First Shooting Test

[Guest]

Hey guys, I have been reading here for a little while. I just got my powder gun out today for the first time and I tested it on an HPP Valve cover for an '89 CR250. I used Extreme Chrome from pbtb as a base coat and Candy Blue over top.

Now, since this was the first time, I was anxious and I know I didn't do all of the step (almost none actually haha). So anyways, I masked and sandblasted the part, coated it with the Chrome and baked it at 400 for 15 minutes. It came out not looking too bad for a first timer. Then I masked the letters and went to shoot the candy blue. It seemed like it was having trouble sticking at first, then started to stick fairly well. As I started to get a thick coat on it, It looked like there were spots in the powder where it wasn't sticking. I baked it anyways(since it's just a test) and it turned out like shown in the pictures below. I know I should have, but I didn't out gas or clean it with any solvents. I think this explains the very slight bubbles in the chrome. Any ideas what could have cause the Candy to turn out like it did? Thanks in advance for all input . Ok, picture time...

Re: My First Shooting Test

What gun are you using?

Also looks like you have a nice out gassing part .

Re: My First Shooting Test

I would say the bubbles are from out gassing and the blotchy look with the blue is because you didn't fully cure the chrome before hot flocking the blue.

What is the best way to make sure it is fully cured?

ok, so basically you think it just wasn't in the oven long enough? And if I read correctly, this makes a lot of sense. I was starting the timer as soon as I put the part in the oven(as if I was baking a pie ). I guess I should be waiting until the part gets up to temp. Would it be a safe bet(until I get an IR gun) to say the part has reached its temp once the powder is melted?

No sir. Find an IR gun and your life will be much easier and less guessing.

Harbor Freight has a cheap one right now. You can do it anyway you want but powder melts and flows around 200f give or take

You can find a nice (low price) IR gun at http://www.mikestoolsusa.net. You may have to call him, it might not be on his web sight. I purchased one from him for $50.00. I think it was a good price, and hope I didnt get robbed. It is a -58 to 930something degree range F.

Thought Id throw it out there, some guns with this range are in the hundreds of dollars. I have had no problem with the gun and it reads 33 degrees everytime I check it with slush (crushed ice and water mix) which is where its supposed to be.

Hope this helps, and no Im not affiliated with this company in any way.

Re: My First Shooting Test

I bought the HF IR gun and sold it to someone else. Its a pile of crap. I compared its reading with a $300+ Fluke model i borrowed from work and found it off +/- 15 degrees in some cases. It was also very poor at reading reflective surfaces like powder.

Save your money and get a mini fluke on ebay for 60 bucks.

Re: My First Shooting Test

updated first post with 2nd round. Still nowhere close to perfect, but much better than the last try. I think I was a little heavy on the chrome, and I put too much Candy on there as well. The masking on the letters was poor too. This tape is kinda hard to work with IMO.

Keep at it. Practice will get you there.

Best of luck.
