…in all these years I did and do repairs in colored boards (paint, resin opaques, swirls)
with fair to excellent results
but I never have been convinced about the tints repairs results; for ex if you ve got to do a larger one that involves the cut lap (darker tone) and the bottom or deck (lighter tone); well, this is not the problem, thats rely on the foam damage (due the translucent effect we need to obtain)
Not sure if I understand, but are you trying to make a tinted, translucent repair? I’ve found that using Q-Cel gives an opaque look to the repair. Cab-o-Sil seems to come out more clear. Also, use a dye to color the fill, rather than a pigment.
My limited experience is that it’s about tint matching and depth. If you’ve got the matching tint, you’ve got to get the same depth. As in the deeper the resin the deeper the color. But I suppose that’s obvious.
Yes I know what you ae talking about, and tints are a bitch to colour match, I too have only hever had satisfactory - good results.
If your removing glass but no foan dont use filler just replace with extra glass. if foam is gon fill as normal but sand it slightly lower than the existing glass to allow for an extra layer of tinted glass than can be sanded back.
Use a sacrifical layer of glass to add the tint. Sand this right to the edge of the old glass. no overlap at this stage. tape up as close to the old glass as possible. As it your adding another layer of tinted glass over the existing tint the colour will build up and be darker aroung the edges (like a lap) so sand off any excess. Tricky to no sand too far but this comes with practice.
Then I add a a layer of glass with clear resin over the whole lot and proceed as normal from there on in.
On the cut lap if the board is coloured on both sides you do the fist later as above then as another layer were the lap, taping up along the lap line (just like a cut lap) sand the second layer to the very edges of the old glass as before. then clear over the top of that.
Thas how I do it, I taught myself so there may be better ways.
If you dont have the right colour try contacting the glasser for advise on what colour they used, or use a pantone colour chart to get a match. do a test to check the cured resin is the same befor glassing the repair.
Its a lot of extra work for sure but if the board is nice then its worth it.
Tints are by far the hardest to repair, I got a swirl I glassed and the owner lost the board off the roof of is car and has bought it back to me to repair and colour match I do these in a similar way so could take some pics.
I’m also open to trying any other ways if any one else has any tips.
Im a builder not a repair man, but in these years I repaired lot of boards (more than 1000)
like I said before is in the quality of the repair that Im concerned
like N V B say, if you need to fill the hole with Aerosil or whatever, is very difficult (for me at least) to obtain a “perfect” repair (visually)
sometimes you dont need to use a filler but the foam is “grainy”. And if you sand a bit to smooth out the thing, still is difficult to obtain the proper depth in the color lam
