Re: Enamel paint on underseal
Can't imagine that any paint will adhere to bituminous underseal without cracking or crazing - certainly wasn't in good condition on mine when I got it.

Re: Enamel paint on underseal
If you mean overpaintable stonechip then no its fine, I have just done my inside floorpan with epoxy mastic 121, a coat of Gravitex and couple of coats of Tekaloid.
If its old or normal bitumen underseal externally then it obviously wont even adhere.

It’s a stone chip then I’ll be painting on top with enamel paint synthetic

Re: Enamel paint on underseal
stone chip is designed so that it can be overpainted,just try a bit where it can't be seen,if its oil based coach paint then it may go on top of normal underseal,again just try it somewhere.

Re: Enamel paint on underseal
I have painted stonechip on mine, but I've always thought of stonechip and underseal as two different things. If you have bituminous underseal which is hard enough to form a sound base for paint I suspect it will be susceptible to cracking and water retention - it was intended to protect by staying flexible, but tends to harden in time.
