Problem with KRYLON paints

[Bucky]

I recently painted a Jeep Honcho with KRYLON Gloss Khaki:

This was shot over Plastikote primer. It laid down super smooth.

I had it up to this point:

Then.......I shot KRYLON Gloss Crystal Clear on the hood:

It started to wrinkle before I got through! I immediately stopped spraying. I'm glad I didn't start with the

body, or I wudda lost the decals, most likely!

When I stripped this hood in the Super Clean, it all peeled off in a sheet. 

Any ideas what might have happened here?

I shot for the first time ever Krylon Fusion over Duplicolor sandable grey primer..Went on smooth the shot with Duplicolor Acrylic Enamel(tall black label can)  I was worried but came out good..Dry quick and smells like lacquer but smooth like enamel..Week and half later wet sand 2000 then 4000 then polish with Meguiar's Scratch X2.0 then finish with Meguiar's Gold class paste..Its the yellow car in the picture...Both cars were cleared with the Duplicolor Acrylic Enamel..and polished the same..

Those look great, Wayne! I think I have some of the Dupicolor clear hanging around. If not, I know I can get some close by.

I'm wondering why the Krylon clear did that over the Krylon tan? I would have thought the same brand would be a good match.

The KRYLON I used is ColorMaster.

Bucky I think its just a BLAH_BLAH_BLAH_BLAH shoot with Krylon..That why I was a little doubtful of using it..I liked the yellow so I tried it and it came out okay..Will be worried again when I try it another color but why not..

[Bucky]

Part of the "live-and-learn" process, I guess! LOL

I would say, just repaint the hood and forget the clear. It looks great as it is!

I believe that Krylon paints have a "window" where you can recoat. Something like within 12 hours and after a few days....

The cans I have mention on the label to recoat within 2 hours, or wait at least 48 hours. It was about 60 hours between color and clear for this shoot.

If I can get the same smooth spray with the tan that I had the first time, I may not try a clear, and just give the whole project a good waxing.

I have had the same thing happen to me.  I can't explain why, but have never used that clear again.  I use Future pretty much exclusively, but even that has messed up a paint job on an occasion or two.

It may be nothing you did or didn't do.  When I build, I fully expect that some paint jobs will get screwed up for a host of reasons, and in some instances, I will have no clue.  To me, it's just the luck of the draw.

I agree with that. I had a color coat wrinkle up using MCW paint over Duplicolor primer. I stripped it, used the same primer, and then shot the MCW again, with good results! Go figure, right?

Sorry to see that happen to you, and very glad you didn't lose your decals on the body. That would have been a bad double bite.

This is another reminder why it's always good practice to TEST combining different materials you haven't used together before...exactly...BEFORE you go on to shoot a model.

It can be a pain to keep stripping a test body for re-use, but it beats having to strip a model you care about, or risk losing (sometimes) irreplaceable decals.

Absolutely correct! I got in a bit of a hurry, I guess. Didn't really think the same brand stuff would do that.

Would a spoon test show this problem?  

[Bucky]

Most likely it would have. Sometimes, I use left over sprue from the same kit, but this time I din't do any testing.

I got that hood re-shot:

It went on smooth again. I may not clear it, this time. After it cures a few days, I might just hit it with some wax, and call it "DUN".

I wonder if Testors Wet Look clear would cover without issue- try on some scrap plastic painted with Krylon before shooting the model.

[Bucky]

I'm gonna try some tests, when I get a minute.

I have a few different clear coat brands to try over this Krylon.

I really like how smooth the Krylon lays down.
