Just bought a grp box trailer and the gelcoat surface is pretty much dry cracked and crazed all over. What's the best way to seal and get a smooth surface to paint it.


Was thinking of sanding it, painting on some resin, flatting that and painting it.


Any advice appreciated, it's several square meters of surface.

Kip is probably the best person to answer this, but if it was me, I would be sanding all the cracked gelcoat off, fill as needed, etch prime, then high build primer, flat, then spray in two pack acrylic.


You need to remove the crazing otherwise it will come back no matter what you cover it up with.  The underside will expand and contract at a different rate to the surface.

Yeh might give kip a call tomorrow.


Was thinking if I sanded it, then painted with something like resin it would get in behind and bond all the loose gelcoat, which could then sand and fill and paint. But sanding resin is going to be a sod

Another option maybe to vinyl wrap to hide the crazing
