Title: preparation of perspex for painting
Post by: howard spary on December 28, 2016, 05:47:51 pm

Hi fellow modelers
Saw some sound asvice from stavros regarding preparation for painting perspex , on the speedline tamar there are lots of perspex sheet components to be painted , wonder if there is any other way which would not require  rubbing down every  part before using  a etch primer and then top coat

look forward to any suggestions
Wish all fellow modelers a happy new year (lots of new models wife permitting

You don't want etching primer- that's acid based for metal parts. You want a plastic primer, which keys to the plastic. Auto paint suppliers sell it if you want it in tin form, or you can buy it in aerosol form from Halfords.

Hi, due to the glossy and hard nature of perspex (acrylic sheet) it really does need to be thoroughly rubbed down until there is no more gloss left and being hard most primers other than etch will not bite without a good sand once you have taken the gloss off it it will accept just about any auto primer you like or as subculture mentioned you could use a plastic primer.
