Modding Clear Coat doing something strange

Hello, I was recently painting my third layer of clear coat when suddenly, after about 6 seconds, the clear started scruntching up and making wrinkles.



Does anybody know why it did this? I guess I will have to sand and start over again. If I do sand with wet 1500 grit, will I have to reapply the gloss black or can I just start adding clear coat again?

 

There are many reasons this happenes.
1. Old paint, you nead a new can.
2. It is cold out, read the lowest tempurature it can be at and if the temp outside is lower bring out a heater.
3. It is to hot outside,ditto except youl just have to wait till it gets cooler.
4. There is to much clear coat on there, spray it in thiner layers next time.
I think there are a few more but I cant remember.

 

Ah that will explain it perfectly. My workshop is in the 60's while outside is very warm with the sun shining.

Thank you.

 

Maybe the colors react with eachother, might happen with different brands or types (not very common though)

 

no letting the coats dry enough between coats can cause that problem also

 

The above posts are good points as well.

I have seen this happen while using some clear coats that contain urathane, on oil based paints, and vise-versa. Make sure that the base color paint, and your clear coat are not of different chemical make-ups that would normally be used to thin or clean each other. Imagine putting paint stripper on paint.

Also make sure that neither of the paints react with the material you are painting. Such as Petrolium Distolates (spelling?) on plexi-glass or plastic.

Tip: grab a peice of scrap material, ( preferably of same that you are painting), and try painting that first. It will help you to eliminate all the sanding and stripping of a failed attempt on the finished part.

Hope these help.

 

Either its too cold/warm were you painted it, or you didn't give it enough time to dry before you put the next layer of clear on. Happend to me once painting an xbox case.....4 days of work and 100+ bucks of paint ruined because I wanted to see it finish ( I paint with Automotive paint, House of Kolor is the brand)

 

Yea, sanding away all that work stinks. I still see some embedded scratches in the frame so I am probably going to switch over to the beginning with 120 grit.
