Problems with paint

Bill_Gilroy · February 15th, 2010, 22:40

I was in the process of spray painting a gun I have, I did a coat of OD a few months ago and it came out great, however it got boreing so i decided to do a CADPAT style. I cut the stencils, put them down, intending for OD to be the bottom layer, I put on a coat of brown and left it. I came back about 15 minuts later to check on it and what appeard to be a spider web was all over it, I figured there was something on the gun like an oil or something so i sanded and cleaned it after it was dry. When I went to do it again after the gun was cleand off it still happend. Does anyone know whats happening and how i can fix it? :banghead:

Sounds like residual silicone lube. Make sure to thoroughly wash the part to be painted;with a suitable solvent, or warm-dishsoapy water (if part is susceptable to solvent damage).

Also, did you sand the surfaces to be painted? If not the paint may not adhere as well to the surface and cause imperfections. How light/heavy are you applying the paint? And are you spraying from an angle or straight ahead?

It didint start until the brown paint went down for some reason so no sanding, and im doin it in several thin coats straight on

Are ya using the same type of paint for all your colours?

If paints are different (say a laquer sprayed over an enamel or acrylic), the solvents / propellants in one, will usually mess up the other.

Sometimes this will happen with the same paint aswell (Krylon has a nasty habit of the next coats, messing up the first coats).

Tremclad is good working cheap stuff. Their satin clear, when sprayed light and dry, gives a good matt finish. The stuff buffs well too.

Ya, I caught the different types of paint as well, chemical reaction between them is causing the spider web.

Im useing the same kind of paint, however it is Krylon camo but ive never had this problem when i was painting my mag or other attachable stuff

How much time do you give it to cure?

The problem its a paint match, the third paint is too strong for the first one. Take a same paint for all layout of your desing. Silicone create a fish-eye, wash your gun with soft thinner, gunwash or lavage final ( CAUTION THINNER ITS TOO STRONG FOR PAINT DONT WASH THE PAINT WITH THAT) . Check a temperature to. 21 Celsius is the best for painting. Sanding your peaces in first of all for max paint grip.

To try again the paint job: sand the spyder web with a 400 or 600 gr, wash that and applique a primer over the old coat . After, you are ready for a desing.

I ave my diploma in Industrial and aerospace paint.

Thanks for the advice everyone, I figure I'll just sand the living crap out of it and primer it and try again.
Cheers

Are you using the krylon fusion camo paint?

Bill_Gilroy · February 17th, 2010, 18:10

Yea, OD was first and brown was when it started to fuster cluck

Put on a layer, matte clearcoat. Put on your second layer.

I think that'll simply accelerate paint chipping.
