Hi All any had their early or late bay hinged GRP roof re gel coated . Mines flaked in patches down the the fibreglass and it could do with a sand down and re coating exterior and interior sides . Anyone had this done professionally by a GRP repair shop, what kind of money is involved? tars
What primer should you use over the original gel coat, before applying 2k paint. a filler primer or etch prime etc
My mate that's sprayed a fair few kit cars recommended epoxy followed by a high build which is exactly what I've done on my baja kit:
Epoxy sticks to gelcoat pretty well. Basically even car body filler will do to fill in the gelcoat holes - you could steam clean the bare patches to get rid of mouldy stuff, then when its all dry and clean, you fill it . For the ultimate stickiness, you can get epoxy filler but its expensive.
