I am constructing a vehicle out of Plastruct or similar styrene or ABS sheet which may be subject to a few knocks in the outdoor environment in which it will run. It will also be frequently handled in the transfer from secure storage to the running line and vice versa.
The particular angle and box sections I need are only available in white or grey and I want to paint them black. My past experience of painting white styrene black for outdoor use has shown that the paint chips all too easily and reveals the white colour underneath.
Has anybody got experience of a type of paint or primer which will slightly etch or adhere to this material for a situation where a fair amount of handling takes place?
Thank you in anticipation.
