I own a '73 scmimtar that has faded worn out paint. I've been trying to find a spray shop that will spray it - but no-one is interested! Im amazed at this but its true. So im doing it myself - i already did a spitfire a few years back so am nota complete novice. SPitfire respray was bare metal - this one I am just flatting off with 300-400. Its only been resprayed once before so the paint is very thin and body is great apart from some tiny minor srress cracks around badges etc. Question is, should i use an isolater coat first? What combination of primers/fillers etc would anyone reccommed for GRP... i'll be finishing in cellulose. Thanks for any advice people.
Go to your nearest yacht chandlers and get an Internatinal leaflet/booklet. You should find everything you know in it - most boats are made of fibreglass.
