My first PBG build TL-1TB

[Sonic Mountain]

I'm almost done, paint is Mitsubishi blue mica, stars are quicksilver, 12 coats of clear. Unfortunately the last coats were color spec crystal clear from Supercheap, DON'T USE IT UNLESS YOU HAVE A MONTH TO WAIT.

Did you do 12 coats of clear over 12 weeks? You should figure on at least a month for finishing anyway to do a really good job of it.

I use these products a lot and that sounds a lot like the application was too thick or the conditions were not ideal for spraying.

If you put it on too thick the top will dry and essentially seal in the rest of the solvent, which has the potential to cause a number of issues, super long curing period being one of them. It can also lead to wrinkling and crazing later on.

FWIW with rattle can automotive acrylic lacquer I spray 3 light coats in opposing directions with 2 or 3 minutes in between each to let it flash off a little. Let that dry, usually a week but if I'm impatient, sometimes 48 hrs. Then light knock back with 800-1500 ish (what ever I have handy usually ) then repeat above.

I'll normally try to empty the entire can over the course of a few weeks, then let it go really hard over a couple of weeks before cutting and polishing.

If you rush it, you will tend to get a lot of 'sink back' into the grain a couple of months down the track.

The good news is though that its is really easy to patch and repair with, you could potentially give it a knock back and spray some new top coats down the track.

Cheers, sonic. I did the 12 coats over 4 days, that's usually fine on a car using duracryl. Guess maybe the timber holds the thinners a lot longer than panel work.
It's not a problem just an annoyance, I'll knock it back in a month add some slip transfers and top it off with some fresh clear.
