Tbar Posted April 12, 2014 Report Share Posted April 12, 2014 Hi all, I've just started using auto air spray paints with an air brush on some plastic hard baits. When I looked through the auto air catalog, it advised using an 'adhesion promoter' before spraying a base coat on the plastic. Does anyone have any experience of this or is this step even necessary. I've never seen anyone do this in any of the 'how to' videos I've watched on the web. Also, if it's necessary, what brand and how much etc. Thanks, Tony.

gone2long Posted April 12, 2014 Report Share Posted April 12, 2014 As far as hard baits are concerned I think proper cleaning is more important than anything now I have no experience with other types of material such as PVC or some of the resins used so you may need to with those.

BobP Posted April 12, 2014 Report Share Posted April 12, 2014 Google "paint adhesion promoter" for lots of info, including a few YouTube demos. I think it's true that a majority of hobby plastic lure painters don't use one, opting instead to dip the lure in acetone (which may not promote adhesion but will certainly clean oily contaminants off) or lightly sanding the blank to give the paint something to grip. Painting lures is different in that we topcoat paint with a durable waterproof product. As long as the topcoat is not breached, the paint will stay where you put it. If it is, nothing much will save the paint, especially acrylic latex paint, anyway. Quote Link to comment Share on other sites More sharing options...
RAswimmers Posted April 18, 2014 Report Share Posted April 18, 2014 I recently started using bulldog adhesion promoter and the stuff works great. I clean the blanks in warm soapy water two times then rinse and dry them with a lint free cloth. Spray it on lightly for the first coat then a little heavier on the second. I haven't had any problems since. Quote Link to comment Share on other sites More sharing options...
woodieb8 Posted April 18, 2014 Report Share Posted April 18, 2014 a good white primer or lacquer prime . your primer will bite on and your colors bite to the prime. its like a sandwhich. Quote Link to comment Share on other sites More sharing options...
Tbar Posted April 20, 2014 Author Report Share Posted April 20, 2014 Thanks for all the input lads. Food for thought. I've washed some cranks in soapy water, dried them, under coated them with white auto air base coat and then coloured them and dipped them in mcu. I'm very pleased with the outcome.
