Stone chip spray application advice

[salim_uk]

Hi gents,
I bought a van with minor rust marks on the sill.

I sanded the rust spots down and applied rust preventer & then sprayed stone chip spray paint from a can onto the whole sill.

It was intermittent spotting with rain on warm day (typical english summer!).

Now in some places, air pocket bubbles have appeared the size of a 5p & 20p coins in several places.

some of those bubbles have what looks like rust stains.

Any ideas or tips etc would be kindly appreciated.

Thanks

Is it like a scutch type spray,?
Or like normal paint,?
did you let the rust stuff dry properly first,? It may need 24hrs or so maybe,,,
I think you may have to remove it and respray tbh.

Rub it back and re spray it on a dry day

Thank you for the replies gents.
It was some water based rust proofer that I purchased from Toolstation.

I had sanded existing rust spots back to bare metal before applying rust proofer.
I allowed it to dry for a couple of days.

But I did NOT spray any paint over the rust proofer before apply stone chip from spray can.

Is it neccary to apply paint or not before applying stone chip?

You may need to apply a primer..after the rust proofer
