Paint problem
« on: March 08, 2011, 05:40:46 PM »

Hi Guy's,
I wonder if anyone can help? I am building a Caldercraft Peggy and have painted the fibre glass cabin with tamiya acrylic but it keeps chipping off. Should I have done anything to the surface prior to painting or have I used the wrong type of paint. If so could someone tell me what paint I should have used. I am at the moment stripping all the paint off and I am glad I discovered this before I painted the hull.
Any help would be much appreciated.

did you not sand down the gel coat before you applied the paint ?

It always pays to thoroughly degrease grp parts as they will still have release agent on them, rubbing down will not get rid of it all and on the Peggy. you may lose some of the rivet detail :-))

I clean the parts with good old CIF and a cloth, then a good wash in soapy water and a green scouring pad, rinse VERY well and leave to dry.
Then a good wipe down with thinners, dry, and it`s ready to paint.Works every time for me :-))

hi Bob. personally i would rub fibre glass down with a fine scotch brite ( a green pan scourer, an old 1 is best as it wont scratch too deeply). use this with warm soapy water. this will remove any release agent & also take the gloss of the gel coat. without loosing any rivet detail. Then rinse well with clean water & leave to dry.

Cheers Glenn

Bri beat me to it, I would advise caution using thinners on fibre glass, as it can eat into it sometimes. That said its fine to use, just dont soak it too much, or try it on a small peice first.  :-))

If your not fast your last mate {-)
The green scourer is a fantastic invention and ideal for prepairing painting surfaces :-))

Hi Bob
I use Tamiya acrylics a lot for detailing my boats.
I always rub down the surface first and then I prime it prior to using the acrylics.
Tamiya recommend priming before using acrylics.  :-))

as several have pointed out a good old scotchbrite or similar will provide a good key for further paint, a squirt of washing up liquid in your rubbing water will also help. A dust coat of primer won't do any harm as it will give a nice surface for the colour coats to stick to. Just be carefull when buying scotchbrites or similar SWIMBO may think you are offering to do the washing up.  %) {-) %%
