VHT wheel paint crackling

[spongbob]

I am in the process of painting some steel wheels with VHT wheel paint (spray can) I prepped them well, followed instructions etc. They came out great except for a small spot that crinkled up on the third coat. I watched it happen. I decided to leave it for 48-60 hours. I hit it with my fingernail and it flaked off, then feathered it out with a scotch brite and shot just that spot again. Right away it did it again. Wondering whats going on???? I have spray painted a TON of stuff and get excellent results 99% of the time

You hit a rotton spot in the old paint .it's caused by solvents lifting . To prevent that your supposed to use a sealer primer under the new top coat ( vht) ..all you need is to sand the bad spot that lifted shoot a spot of thr Said sealer primer"... over the areas in question leave about 30% overlap... allow maybe and hour re coat with the vht. As far as the vht they are good paints that are avialible at auto store and online vht " is loved by hot Rodders and repair shops alike " ok not as good as powder coat but dang I've seen powder coat lift (schale) and flake from expansion or technique ?....
